Foundation Inspection in McKinney, TX

A foundation inspection McKinney homeowners request usually means one of two things: a free on-site look from a repair contractor that ends in a written estimate, or a paid report from an independent structural engineer. This page explains both, what happens during each, and when the City of McKinney requires the second one. The short version is that any McKinney home with a crack that keeps growing, a door that has stopped latching, or a floor that slopes toward one corner should get the free inspection first, and any home that then needs piers or leveling will also need the engineer.

To book a free inspection, call (972) 555-0100. A crew lead comes out the same week in most cases, walks the house with you, and leaves a written, itemized estimate. If the house does not need work, the estimate says so.

Signs you need a foundation inspection in McKinney

• Stair-step cracks climbing the mortar joints of the brick, covered on the cracks in brick page
• Interior doors that stick in summer and swing freely in winter, or the reverse, covered under sticking doors and windows
• A gap opening between the brick and the window or door frames
• A floor that slopes, or a marble that rolls to the same corner every time, covered under sagging floors
• Cracks in drywall that run diagonally from the corners of doors and windows
• A crack in the garage slab or patio that has widened over one wet-dry cycle
• Separation between the chimney and the wall it stands against

One of these alone is not proof of a problem. Two or three together on the same side of the house usually are, and that is the pattern described on the sinking foundation page.

What a foundation inspection involves in McKinney

The inspector starts outside, walking the full perimeter and noting every crack in brick, mortar and exposed slab edge, plus the grading, gutters, downspouts and any trees close to the foundation. Inside, the main tool is an elevation survey, which measures how far each part of the floor sits above or below a reference point so the inspector can map where the slab has dropped or heaved. Doors and windows are checked for square. On a pier and beam house, which in McKinney mostly means the late 1800s and early 1900s homes near the historic downtown square that Dustin Pitts Realty describes, the inspector goes under the house to check piers, beams, joists and moisture. Most McKinney homes are slab-on-ground; the Texas Section of ASCE says the majority of Texas foundations are, and the median McKinney home was built in 2007 according to the Census Bureau’s ACS 2024 figures, so a typical inspection here is a slab inspection.

The findings go into a written estimate that says what moved, how far, the likely cause, and what the repair would involve, pier by pier. Where movement is small and the cause is watering or drainage, the estimate can say to fix the water and re-check in a season.

The engineer’s role is separate. The City of McKinney Building Inspections guidelines require a permit for any foundation leveling, pier or footing replacement, shimming or floor system replacement, and the application must include an engineer’s letter and drawings showing the affected areas and whether plumbing will need testing. The city closes the permit only after the final engineer’s report is uploaded to its CSS portal. That engineer must be licensed and registered in Texas. Engineers here generally work to the Texas Section of ASCE’s Guidelines for the Evaluation and Repair of Residential Foundations, now in Version 3, effective April 1, 2022.

Free contractor inspection or paid engineer’s report?

Both, in that order, for most repair jobs. The contractor’s inspection is free because it is also how the contractor bids the job, and This Old House’s 2026 inspection guide is direct about that: a free inspection from the company that wants to sell you piers is not an independent opinion. That is fair. The answer is to get the written estimate, then have an engineer who does not sell repairs confirm the plan before the permit is filed. The engineer’s letter is required by the city anyway, so the second opinion costs nothing extra beyond the report you already need. For a small crack seal with no piers, the free inspection is usually enough.

Foundation inspection McKinney cost ranges from the guides

The contractor visit is free. For the engineer, This Old House’s 2026 guide puts a structural engineer’s foundation inspection at $300 to $1,000 with a national average of $600, billed at $100 to $500 per hour. HomeAdvisor’s 2026 figure is $340 to $780, Modernize’s is $500 to $1,000, and Fixr’s 2026 range runs to $2,000 for extended investigations. A separate soil report, if the engineer asks for one, is $500 to $3,000 in This Old House’s table.

Your written estimate lists the engineer’s report as its own line, apart from the repair.

An inspection ends with one of a few next steps. If the slab has settled, the answer is usually piers, covered on the foundation repair page and priced on the foundation repair cost page. If the movement is minor and the cracks are the whole problem, foundation crack repair seals them without piers. If the house is dropping on one side and the elevation survey shows it, read about a sinking foundation. And if the cause is dry soil pulling away from the slab, which the USDA NRCS says happens as Houston Black clay opens cracks 1/2 to 4 inches wide at 12 inches deep in dry periods, foundation watering may be the first fix.

A foundation inspection McKinney homeowners can act on is one that measures instead of guesses, puts the numbers in writing, and tells you honestly when the right move is to water the soil and wait. Estimates are free and written, crews are insured, and every job carries a written warranty.
