Construction in San Dimas, CA
Kitchen remodeling in San Dimas typically runs $14,000-$45,000 for a full gut-and-rebuild, and most jobs hit the higher end on hillside lots where 1950s-1970s slab foundations and pre-code framing drive up labor. Homes in the southern flatlands are dense tract builds from the mid-century, while the northern foothills hold custom homes with post-and-pier foundations and wood-shake roofs that complicate any permitted work. Call (470) 298-9650 for a written, line-item price before anyone starts.
Why San Dimas Homes Are Different
San Dimas is two housing markets in one. The southern flatlands, west of San Dimas Avenue and down toward the 57, hold 1950s-1970s tract homes: original wood-frame construction, aging stucco, slab-on-grade foundations. These houses were built fast and cheap, and sixty years later the bathrooms and kitchens are still on their original copper supply lines and cast-iron drains. Hillside and canyon-adjacent neighborhoods to the north sit inside the Very High Fire Hazard Severity Zone at the base of the San Gabriel Mountains. That means CAL FIRE and LA County fire-hardening rules govern nearly every roof replacement, exterior remodel, or addition: Class A roofing assemblies, ember-resistant soffit venting, non-combustible eave details. Contractors who treat fire-resistant construction as an upgrade rather than the default pricing assumption will underbid the job and come back with change orders. We write the price with the fire-hardening requirements already in it, because in San Dimas they are not optional.
Santa Ana winds funnel through the foothills here at higher velocities than in La Verne or Covina, so wind-load engineering affects roofing and exterior wall assemblies. The same terrain channels storm runoff and occasional debris flows from the mountains, making drainage and grading design critical on any lot touching the canyon slopes. And the northern foothill tracts sit on expansive clay soils that swell and shrink with seasonal moisture, so skipping a soils report on an addition or ADU practically guarantees foundation movement within a few years. These are solvable problems, but they have to be priced and planned before anyone picks up a tool.
Our Main San Dimas Services
San Dimas homeowners call us most about two projects that sit outside the five construction trades on this page: fencing and hardscape. Both are governed by hillside slope, soil movement, and fire-zone setback rules specific to San Dimas.
Fence Installation in San Dimas
San Dimas fence work is shaped by topography and wind. On hillside lots, post depth and concrete footings have to be engineered for sloped ground and expansive clay that shifts through wet-dry cycles; a fence set in shallow concrete on a canyon slope will lean within two seasons. Santa Ana winds punish tall privacy fences on exposed ridgelines, so we size posts and rails for wind load rather than just panel height. Vinyl fence installation in San Dimas runs $3,500-$9,000, and aluminum runs $4,000-$10,000 depending on slope and linear footage. See Fence Installation in San Dimas for full pricing.

Driveway & Pavers in San Dimas
Driveways in San Dimas deal with two problems flatland cities do not: expansive clay under the slab and storm runoff from the foothills. Poor subgrade preparation on clay soil cracks concrete within a few years, so we compact and sometimes over-excavate before placing anything. Paver driveways run $7,000-$18,000, concrete runs $4,500-$12,000, and paver patios run $3,500-$11,000. Every quote includes a written scope and a documented photo record before and after. See Driveway & Pavers in San Dimas for the full breakdown.

Before
AfterKitchen Remodeling in San Dimas


A kitchen remodel in San Dimas costs $14,000-$45,000, with most mid-century tract homes in the southern flatlands landing between $20,000 and $35,000 because the plumbing, electrical, and framing were never updated. Hillside custom homes push higher: fire-zone eave details, older post-and-pier foundations, and more complex structural openings all add labor the square footage alone would not suggest. We write the price before work starts, and no change proceeds without a signed change order, which is why projects finish within a few percent of the number the customer agreed to. Our full process is documented on the Kitchen Remodeling page.
Cabinets & Countertops
Signs you need it
Doors that no longer close square, particleboard boxes swelling from sink leaks, or laminate counters separating at the seams are the three tells we see most in San Dimas tract kitchens.
What it costs in San Dimas
Cabinet installation runs $4,000-$13,000 and countertop installation runs $2,000-$6,500, depending on whether you are keeping the existing layout or moving plumbing and electrical.
How we do it
We measure the existing layout, quote flat written pricing using brands like KraftMaid for cabinets and Cambria for stone, then replace boxes, faces, and counters in that order so you keep a working sink as long as possible.
Full Kitchen Remodeling
Signs you need it
When the floor plan fights how you cook, the plumbing is original cast iron, and the electrical panel cannot support modern appliances, a partial refresh will not fix the underlying problems.
What it costs in San Dimas
A full kitchen remodel in San Dimas runs $14,000-$45,000, with small kitchens in southern San Dimas tract homes starting around $9,000 and hillside custom kitchens running to the top of the range.
How we do it
We open walls to verify framing and plumbing condition, document everything with photos, then rebuild to current code including any fire-zone eave and venting requirements before cabinets go in.
What Kitchen Remodeling Costs in San Dimas
| Item | Typical range in San Dimas |
|---|---|
| Full Kitchen Remodel | $14,000-$45,000 |
| Small Kitchen Remodel | $9,000-$20,000 |
| Cabinet Installation | $4,000-$13,000 |
Can you remodel my San Dimas kitchen during fire season?
Yes, but exterior work and any roof or eave changes in the VHFHSZ may need scheduling around red flag warnings and county inspection backlogs. Interior kitchen work is not restricted, and we price the fire-hardening items into the written quote from day one.
Will the price change once you open my walls?
Only if we find a condition that could not have been seen in the written estimate, and even then no change proceeds without a signed change order. You will see the new number in writing before we do the work. Call (470) 298-9650 for an exact quote.
Bathroom Remodeling in San Dimas


A bathroom remodel in San Dimas runs $9,000-$28,000, with small hall baths in 1950s-1970s tract homes starting around $5,000 and primary suites in hillside customs reaching the top of the range. Original cast-iron drains and undersized exhaust fans are the two conditions we find in nearly every mid-century San Dimas bathroom, and both have to be fixed before tile goes up. Our written quote covers the scope in full, and you can see the full process on the Bathroom Remodeling page.
Walk-In Showers & Shower Remodeling
Signs you need it
Grout that stays dark after cleaning, a pan that flexes underfoot, or a shower that cannot maintain temperature are signs the waterproofing membrane or the valve is failing.
What it costs in San Dimas
A walk-in shower installation in San Dimas runs $4,500-$12,000, and a shower replacement runs $3,000-$8,500 depending on whether the pan and drain need to be reset in concrete.
How we do it
We remove to the studs and subfloor, inspect and replace the valve and drain, install a new waterproof membrane, then tile and grout so water stays inside the assembly, not behind it.
Tub-to-Shower Conversion
Signs you need it
If the tub is rarely used, the finish is worn through, or the surround is leaking at the corners, a tub-to-shower conversion often costs less than repairing the tub and its plumbing.
What it costs in San Dimas
A tub-to-shower conversion in San Dimas runs $3,500-$10,000, with the final number depending on whether the drain line has to be re-routed for a shower pan.
How we do it
We pull the tub, inspect the subfloor and drain slope, set the new shower pan, build the waterproof membrane up the walls, and tile to the new opening.
What Bathroom Remodeling Costs in San Dimas
| Item | Typical range in San Dimas |
|---|---|
| Bathroom Remodel | $9,000-$28,000 |
| Small Bathroom Remodel | $5,000-$12,000 |
| Walk-In Shower Installation | $4,500-$12,000 |
Do I need a permit to remodel a bathroom in San Dimas?
Yes, any work that touches plumbing, electrical, or the drain line requires a permit through LA County Building and Safety, and we pull permits on every permitted job. The permit cost is included in the written quote, not added later.
How long does a bathroom remodel take in San Dimas?
A hall bath typically takes two to three weeks, a primary suite four to six, depending on inspection scheduling through the county office serving San Dimas. Call (470) 298-9650 and we will give you a written schedule with the price.
Roofing in San Dimas


Roof replacement in San Dimas runs $8,000-$20,000, and on hillside homes inside the Very High Fire Hazard Severity Zone the number is almost always pushed higher by Class A assembly requirements and ember-resistant venting. Metal roof installation runs $15,000-$40,000, and tile roof repair runs $600-$2,500. All of our roofing work carries the Roofing service documentation, including a written warranty and a documented photo record of what was found and what was done.
Roof Replacement & Installation
Signs you need it
Granules collecting in gutters, shingles lifting at the rake edges, or a roof with more than two layers of existing covering all point to full replacement rather than repair in San Dimas wind conditions.
What it costs in San Dimas
A roof replacement in San Dimas runs $8,000-$20,000, with flatland tract homes at the lower end and hillside custom homes with fire-zone assemblies and steep access at the top.
How we do it
We remove the existing layers to the deck, document what is underneath with photos, install the underlayment and Class A rated assembly, and bring all eave, soffit, and venting details to current fire code.
Roof Repair
Signs you need it
A ceiling stain, a shingle that lifted after a Santa Ana event, or flashing pulling away at a chimney or wall intersection are all repairs that get worse and cheaper to fix early.
What it costs in San Dimas
A roof repair in San Dimas runs $400-$1,800, and a tile roof repair runs $600-$2,500, depending on whether the underlayment is intact and how many tiles have to be reset.
How we do it
We identify the water path at the roof level, not just the interior stain, replace the damaged material and any failed flashing, and photograph everything before sealing the repair.
What Roofing Costs in San Dimas
| Item | Typical range in San Dimas |
|---|---|
| Roof Replacement | $8,000-$20,000 |
| Metal Roof Installation | $15,000-$40,000 |
| Roof Repair | $400-$1,800 |
Does my San Dimas roof have to meet fire code?
If your home sits in the VHFHSZ north of the flatlands, yes, the roof assembly, eave details, and soffit venting all have to meet CAL FIRE hardening standards. We price those requirements into every hillside quote, not as a change order later.
Can roof work be done during high wind events in San Dimas?
No responsible contractor installs shingles or underlayment during a Santa Ana wind event; even materials rated for the wind load cannot be set correctly while it is blowing. We schedule around forecasts in the foothill corridors. Call (470) 298-9650 for a written quote.
Windows & Doors in San Dimas


Window replacement in San Dimas runs $4,500-$15,000, and impact window installation runs $8,000-$25,000, with the higher end driven by hillside exposure to Santa Ana winds and ember risk in the fire zone. Original 1950s-1970s tract homes usually still have single-pane aluminum frames that lose interior climate fast and do nothing against wind-driven debris. Our process is documented on the Windows & Doors page, and every quote is a written flat price before work starts.
Window Replacement
Signs you need it
Condensation between the glass, frames that rattle in wind, or a room that will not hold its temperature through a Santa Ana event mean the window seal or frame has failed.
What it costs in San Dimas
Window replacement in San Dimas runs $4,500-$15,000, depending on how many openings, whether the exterior is stucco or wood siding, and whether the frames need new flashing to meet fire-zone standards.
How we do it
We remove to the rough opening, repair any rotted framing we find, set the new window on fresh flashing, and seal the exterior to shed wind-driven rain at the foothill wind speeds.
Impact Windows & Doors
Signs you need it
If you are on an exposed ridgeline or canyon-corridor lot in the VHFHSZ, impact-rated glass is worth pricing alongside standard replacement windows for the wind-load and ember protection difference.
What it costs in San Dimas
Impact window installation in San Dimas runs $8,000-$25,000, with the number set by opening count, glass area, and whether the doors also need impact-rated frames.
How we do it
We measure each opening, quote the impact-rated assembly in writing, then install the frames, glass, and hardware as a unit with the manufacturer’s full warranty on file for you.
What Windows & Doors Costs in San Dimas
| Item | Typical range in San Dimas |
|---|---|
| Window Replacement | $4,500-$15,000 |
| Impact Window Installation | $8,000-$25,000 |
| Door Installation | $4,500-$15,000 |
Do impact windows make sense on a flatland tract home in San Dimas?
Usually not, unless the lot faces an open drainage channel or the foothill wind funnel directly. On flatland homes standard energy-efficient windows with good flashing are the better cost-to-benefit. Call (470) 298-9650 for a line-item comparison.
Will replacing windows change my stucco exterior?
Yes, the stucco around each opening gets cut back to allow new flashing and a clean seal, then patched and matched. It is included in the written price, not billed as a separate line item afterward.
Home Additions & ADU in San Dimas

A home addition in San Dimas runs $45,000-$130,000, and ADU construction runs $90,000-$220,000, with hillside lots pushing higher due to expansive clay soils, fire-zone eave and venting rules, and post-and-pier foundation conditions that predate modern seismic standards. Skipping a soils report on a northern San Dimas address almost guarantees slab movement within a few years, so we price the report and an engineered foundation into every hillside quote. The full process is on the Home Additions & ADU page.
ADU Design & Permitting
Signs you need it
When a San Dimas homeowner wants a rentable unit, an in-law room, or a workspace that current setback and fire-zone rules will not allow as an attached add-on, a permitted ADU is usually the faster path.
What it costs in San Dimas
ADU construction in San Dimas runs $90,000-$220,000, with design and permitting typically consuming the first 10-15% of that before construction starts.
How we do it
We order the soils report if the site is on clay, work through LA County plan check, pull the permits, and only then write the construction price against the approved drawings.
Garage Conversion ADU
Signs you need it
A detached garage with a solid slab, usable framing, and an existing electrical drop is the most predictable ADU conversion in San Dimas when the structure is not too far gone.
What it costs in San Dimas
A garage conversion in San Dimas runs $30,000-$80,000, depending on whether the slab needs replacement, the garage must be fire-hardened, and how much of the existing framing can be reused.
How we do it
We inspect the slab and framing, document the condition in writing and photos, then convert the shell into a conditioned, permitted ADU with its own address and meter path.
What Home Additions & ADU Costs in San Dimas
| Item | Typical range in San Dimas |
|---|---|
| Home Addition | $45,000-$130,000 |
| ADU Construction | $90,000-$220,000 |
| Garage Conversion | $30,000-$80,000 |
Do San Dimas ADUs have to meet fire-hardening rules?
If the ADU is in the VHFHSZ, yes: the roof assembly, eave details, and venting all have to meet the same CAL FIRE standards as the main house. We price those into the ADU quote from the first written estimate.
Will an ADU trigger a reassessment on my San Dimas property tax?
An ADU generally increases the assessed value only on the new square footage, not the entire property, under current state rules, but your tax situation is between you and the county. Ask us for the permit path and we will walk you through it. Call (470) 298-9650 for a written quote.
