Buyer's guide

Foundation Repair Buyer's Guide for Pasadena, Texas

What to do when you suspect foundation damage — how to read the warning signs, what an inspector looks for, what the repair options actually involve, how to choose a contractor, what it costs in this region, and what to do (and not do) after the work is done.

Who this is for

Homeowners who have noticed a crack, a sticking door, or a sloping floor — and want a straight answer before they call a contractor. The guide covers everything from "what does this crack mean" to "should I sign this proposal." Read it top to bottom if you have time; jump to the section you need using the table below.

Section 1

What the warning signs look like

Foundation problems tend to build slowly — a single small sign is rarely a crisis, but a pattern of signs usually means the slab is moving. Here is what contractors look for during an inspection.

Structural signs — the ones that matter most

! Stair-step cracks in exterior brick walls — the most common early sign on Pasadena-area homes
! Vertical or diagonal cracks wider than 1/4 inch inside drywall, especially near doors and windows
! Doors that stick, swing open by themselves, or no longer latch properly
! Windows that stick or have gaps appearing at the top of the frame
! Sloping or visibly uneven floors — use a marble test, place a marble on the floor and see if it rolls
! Gaps between walls and ceiling, or between walls and floor
! A cracked or displaced chimney (the chimney pulls away from the rest of the house as the slab moves)
! Bowing or leaning basement walls (less common on Pasadena slabs, more common in older pier-and-beam homes)

Secondary signs — supporting evidence

Cracks in tile floors (especially grout lines separating or tiles popping loose)
New gaps around exterior doors or windows where trim used to be flush
Siding or brick veneer separating from the house
Garage door frame pulling away from the wall
Water pooling around the foundation after rain instead of draining away
Moldy smells in the crawl space (on pier-and-beam homes, often paired with moisture damage)

How to tell if it is actually getting worse

A single small crack rarely means foundation failure. A pattern of cracks — same wall, same corner, same side of the house — usually means the slab is moving. The biggest concern with cracks is whether they are getting wider month over month. Take a photo, write the date on it with a pencil, and re-check in 30 days.

Section 2

What kind of foundation your home has

The repair options depend entirely on what is under your house. Pasadena has three common foundation types — here is how to identify yours.

Slab-on-grade (post-1970s most common)

A concrete slab poured directly on the prepared ground, typically 4 inches thick with thickened edges. The slab sits on Houston black clay and moves with it. Most common in Pasadena homes built after about 1970.

How to tell

No visible piers or crawl space under the house
Plumbing and electrical enter through the slab
Single-story or two-story, no elevated floor

Common repairs

Underpinning (piers), slab jacking, crack injection, drainage correction

Pier-and-beam (1940s–1970s)

A wood-frame floor structure supported by a series of piers (concrete blocks, poured concrete, or wood) in a crawl space. Beams sit on the piers and carry the floor joists. Common in older Pasadena neighborhoods.

How to tell

Access door on the outside of the house, often at the back or side
Crawl space 18 inches to several feet tall
Floor feels springy or bouncy in places
Musty smell coming through the floor

Common repairs

Replace failing piers, shim beams, sister or replace rotted beams, install vapor barrier

Combination / additions

Homes built or expanded in multiple phases, with different foundation types under different parts of the structure. Common in older Pasadena homes with later additions.

How to tell

Visible floor level changes between rooms or original/added sections
Cracks at the transition between two parts of the house

Common repairs

Match repair method to each section; sometimes requires leveling both sections to a common plane

Section 3

The repair methods, explained plainly

Foundation repair is not a single procedure. It is a set of techniques your contractor selects based on your home, your soil, and your damage pattern. Here is what each one actually involves.

Underpinning (piers or pilings)

1–3 days for most homes; up to a week for larger homes needing 15+ piers

Best for: Homes with measurable settlement — sloping floors, sticking doors, or visible cracks that are getting wider

The most common repair for slab foundations in Pasadena. Steel or concrete supports are installed under the slab and driven to bedrock or load-bearing strata, bypassing the active clay zone. The slab is then lifted back toward level.

Common options in this category

• Push piers — hydraulically driven steel pipe sections. Used when the structure is light enough to drive against.
• Helical piers — steel shafts with welded helix plates, rotated into the ground. Used for heavier loads or specific soil conditions.
• Concrete press pilings — precast concrete cylinders pressed into the ground. Common in older Houston work. Less durable than steel but cheaper.

Slab jacking (mud-jacking or poly-jacking)

A few hours per affected area; can be done same-day

Best for: Void filling, minor settlement caught early, or as a complement to drainage work

A grout mixture (mud-jacking) or expanding polyurethane foam (poly-jacking) is injected under the slab to fill voids and lift the slab in small areas where it has settled. Less invasive than underpinning, but does not address deeper soil movement.

Crack repair (epoxy or polyurethane injection)

A few hours per crack

Best for: Surface cracks in the slab or foundation walls that are not associated with settlement

Cracks are sealed with either epoxy (rigid, structural) or polyurethane (flexible, water-resistant). This does not stop the cause of the crack; it stops water intrusion and prevents further damage. A good repair for cosmetic cracks and minor structural cracks where settlement has stopped.

Pier-and-beam re-shimming and pier replacement

2–5 days depending on access and the number of failing piers

Best for: Homes with crawl spaces where the original piers have settled or the beams have sagged

Failing piers are removed and replaced with new concrete or steel piers, and beams are shimmed back to level. If moisture has rotted a beam, the affected section is reinforced with a sister beam or replaced. Most repairs also recommend a vapor barrier to control moisture going forward.

Drainage and water management

A downspout extension is a 1-hour fix; a perimeter French drain is a multi-day project

Best for: Homes with water pooling against the foundation, or as preventive maintenance to extend the life of an existing repair

Not a structural repair by itself but the most common companion to one. French drains, surface drains, grading corrections, downspout extensions, and root barriers all work to keep soil moisture consistent around the foundation. In Houston black clay, water is the number-one cause of foundation movement — managing it correctly can prevent the next round of settlement.

Section 4

What a real foundation inspection covers

Most reputable inspections take 1.5 to 2.5 hours on site plus a written report within a few days. Here is what the inspector actually does during that visit.

Exterior walk

The inspector walks the perimeter looking for cracks in the brick, gaps around doors and windows, signs of drainage problems, and any visible settlement. Takes about 15 minutes.

Elevation survey

A digital elevation meter measures the slab at multiple points across the house (typically every 5–10 feet along the interior and exterior). The numbers are mapped to identify the low and high spots. Takes 30–60 minutes.

Interior walk

Inside, the inspector documents visible damage — drywall cracks, sticking doors, gaps around trim, sloping floors. Photos are taken for the report.

Crawl space (if applicable)

For pier-and-beam homes, the inspector enters the crawl space and inspects every pier, every beam, looks for moisture, rot, termite damage, plumbing leaks, and ventilation issues. Takes 30–60 minutes.

Drainage review

The inspector notes how water moves around the house — where it pools, where downspouts discharge, where the soil slopes toward the foundation. Often done at the same time as the exterior walk.

Report + recommendation

Most inspections result in a written report within a few days. It should include the elevation map, the photos, the inspector's diagnosis, and a recommended scope of work (or a recommendation to monitor if the problem is minor). Some companies offer the inspection free if you commit to getting a quote from them; others charge $250–500.

Section 5

How to choose a foundation repair contractor

Six checks that distinguish a competent local contractor from a sales operation. Run through this list before you sign anything.

Verify they work in your area

Check: Ask for a list of recent jobs within 5 miles of your address. Foundation repair is highly local — soil conditions, groundwater, and access differ block to block. A company that mostly works 20 miles north of you will not have the same baseline.

Why it matters: Local knowledge translates directly into better diagnoses.

Check they carry the right insurance

Check: Ask for a Certificate of Insurance showing general liability ($1M minimum) and workers' comp. Foundation repair involves heavy equipment and structural work — uninsured contractors are a major liability.

Why it matters: If a worker is hurt on your property and they have no workers' comp, your homeowner's insurance is on the hook.

Ask about engineer involvement

Check: For complex repairs or homes with severe settlement, a structural engineer should be involved in the diagnosis and the repair plan. Some companies have one on staff; others subcontract. Either is fine — what matters is that an engineer reviewed your home and signed off on the plan.

Why it matters: Engineers catch issues that contractors may miss, and the engineer's letter helps with warranty transfers and home sales.

Get a written scope of work

Check: The proposal should name the components (number of piers, locations, type, depth), the method, the timeline, the cleanup, and the warranty. Vague proposals like "we'll fix the foundation" are a red flag.

Why it matters: It is hard to compare quotes or hold anyone to a vague promise.

Compare at least three quotes

Check: Most foundation repair companies offer free quotes. Get three. The right repair plan should be similar across all three; the price should be within about 20%. If one is dramatically lower than the others, ask what they are skipping.

Why it matters: Spread narrows after three competitive bids. Below that, you do not know if you got a fair price.

Read the warranty terms carefully

Check: Foundation repair warranties are typically transferable to the next owner, last 10+ years, and cover the same problem coming back. Read the fine print — "lifetime" can mean company lifetime, not home lifetime.

Why it matters: A warranty that does not transfer is worth less at resale, and a vague one is hard to claim.

Section 6

Cost ranges for the Pasadena / Houston metro

What foundation repair costs in this region, with the actual variables that move a quote up or down. Use this as a sanity check before getting bids.

Service	Per pier (if applicable)	Typical range
Single crack repair (epoxy or polyurethane injection)	—	$300 – $800
Mud-jacking or poly-jacking (small area, 1–2 rooms)	—	$1,000 – $3,000
Pier installation (push or helical), 6–10 piers, typical slab repair	$500 – $1,500 per pier	$7,000 – $15,000
Pier-and-beam re-shimming + pier replacement	$500 – $1,500 per pier	$4,000 – $12,000
Full-perimeter French drain + grading	—	$3,500 – $10,000
Whole-house leveling (slab, 15+ piers, heavy settlement)	—	$15,000 – $30,000+

Foundation repair costs in the Pasadena / Houston metro vary based on the type of repair, the number of piers needed, accessibility of the work area, and the underlying soil conditions. The ranges above are typical for a residential home but actual quotes depend on the elevation survey and the specific damage pattern. Reputable contractors will not give a meaningful price over the phone — they will inspect the property first.

Will homeowner's insurance cover foundation repair?

Almost never for standard settlement. Most policies exclude foundation damage from "earth movement, settling, shrinkage, or expansion of soil." What is sometimes covered: damage from a specific event (a burst pipe that washes out the soil, a fallen tree) or damage that falls under the "perils" section of your policy (fire, wind). Read your policy's section on "earth movement" exclusions or call your agent. Most homeowners pay for foundation repair out of pocket.

Section 7

What to do after the repair

The first 60 days after a repair matter, and the next 10 years matter more. Here is how to keep the repair from failing — and how to make sure the warranty stays valid.

Wait 30–60 days before cosmetic repairs

The slab continues to settle microscopically over the first 4–8 weeks. Most reputable contractors return for a follow-up elevation survey during this window. Hold off on drywall repair, painting over cracks, and tile work until the structure has stabilized.

Watch for: Fresh cracks appearing in new places, doors going from sticking to jamming the wrong way, gaps appearing in places that were tight before.

Keep gutters and downspouts clear

The single biggest thing a homeowner can do to extend the life of a foundation repair. Water is the number-one cause of foundation movement in Houston black clay. Clean gutters twice a year; check downspout discharge points monthly during rainy season.

Watch for: Overflowing gutters during a rainstorm, water pooling against the foundation, downspouts that discharge within 2 feet of the slab edge.

Maintain consistent soil moisture

During dry spells, run a soaker hose 18 inches from the foundation for 30 minutes twice a week. The goal is to keep soil moisture consistent, not wet. Wet-dry cycles are what damage foundations; consistent moisture does not.

Watch for: Soil pulling away from the slab edge (a visible gap forming), widespread cracking in the lawn near the foundation, plants dying in the same area.

Watch the trees

Mature trees within 20 feet of the foundation can draw moisture unevenly from one side, especially oaks and elms. A root barrier (typically 18–24 inches deep) prevents roots from reaching under the foundation and can be installed if trees are causing visible damage.

Watch for: One side of the house settling more than the other, vertical cracks in drywall concentrated near tree locations.

Document the work

Keep the elevation survey, the proposal, the engineer's letter (if any), the invoice, and the warranty in a single folder. When the home sells, the buyer's inspector will ask for it. Most of these documents transfer value (and the warranty) to the next owner.

Watch for: Selling the house without these documents — buyers will discount the price or ask for repairs before closing.

Section 8

Red flags and high-pressure tactics

Things that should make you walk away from a quote immediately. Foundation repair is a mature industry in Houston, and the vast majority of companies are reputable — but the few that are not, are not subtle.

High-pressure sales tactics at the door — a "foundation repair expert" who knocks unsolicited and offers a free inspection is a sales operation, not a contractor
Refusal to provide elevation readings in writing
Cash-only quotes or pressure to decide within 24 hours
No physical address, no website, no reviews outside a sales-page testimonials list
Quoting a full-house pier job without an elevation map showing why it is needed
Asking for a deposit larger than 10% before any work begins
No written warranty, or a "lifetime warranty" tied to the company itself
Painting over cracks during the inspection instead of documenting them
Recommending expensive repairs on a home that has been stable for years with no new damage
