Start calm, start organized
Finding what looks like foundation damage can feel urgent. Usually, though, the useful first move is not a phone call to a repair company but a notebook. Foundation movement tends to unfold slowly, and a clear record of what changed and when is the thing every evaluator will ask for. This guide is arranged in phases, from the day you notice a problem through the season after a repair, so you can see what belongs in each phase and what can wait.
One exception: if you smell gas, hear water running inside a wall, see a crack that is widening by the day, or have a door or window that suddenly jams shut in an exit path, call the utility or a professional right away.
For reference: the Lexington/Bluegrass station
NOAA's engineering weather data for the Lexington/Bluegrass station, at an elevation of 988 feet, gives a 1% summer design temperature of 89°F with a mean coincident wet-bulb temperature of 74°F, and a 99% winter design temperature of 10°F. In an average year at Lexington/Bluegrass, NOAA counts about 459 hours with the wet-bulb temperature above 73°F and about 1,719 hours above 67°F. The station's data also lists a 50-year basic wind speed of 90 mph (3-second gust at 33 feet), a 100-year rainfall rate of 3.0 inches per hour and about 49 freeze-thaw cycles in an average year.
Phase one: steady the situation
Before measuring anything, take care of what is plainly wrong:
- Turn a downspout that empties at the wall so it discharges away from the house.
- Clear any gutter that is overflowing.
- Move stored boxes and valuables away from a damp basement wall.
- Shut off and report any plumbing leak you can find.
None of this commits you to a repair. It simply stops the problem from being fed while you learn more.
Phase two: build a baseline
Pick a day and record the house as it is.
- Photograph each crack you're worried about with a ruler or coin in the frame for scale.
- Draw a short pencil tick at each end of every crack and write the date beside it.
- Measure the widest point and note it.
- List every door and window that sticks, rubs or won't latch.
- In a basement, photograph each wall straight on; in a crawlspace, photograph the piers and beams.
- Read the water meter with every fixture off, then again later in the day.
Keep everything in one place, in date order.
Phase three: test the water explanation
Water is the factor you can change cheaply, so test it next. During the next heavy rain, walk the outside of the house and watch where the water goes. Note gutters spilling over, downspouts discharging close to the footing, water running toward the house across a walk or patio, puddles that linger against the wall, and window wells filling up. Inside, check the basement or crawlspace afterward for new dampness.
After a windstorm, look again for gutters pulled loose and downspout sections knocked off. Fixing the water path is worth doing whatever an evaluator later concludes.
Phase four: tell swelling from structure
Revisit every pencil mark on a regular rhythm and shoot each photo from the same spot so the pictures can be laid side by side. Interior woodwork reacts to moisture in the air: jambs, casing and door slabs swell when the house is damp and give the space back when it dries. A door that rubs along its full length during a sticky spell and closes cleanly later is often reacting to that. A gap that is even along the top of the door one month and tapered the next is a different matter, because a frame racking out of square suggests the structure around it is shifting. Likewise, a crack that opens and closes with the seasons reads differently from one that only ever grows. Jot the date and a word about the weather beside each reading.
Phase five: arrange the evaluation
Once your record covers a meaningful stretch, bring someone in. A repair company's estimator can inspect for free; a structural engineer who doesn't sell repairs will charge for a site visit and a written report but has no stake in the method. Hand over your notebook either way, and ask for a written finding: what is moving, what is causing it, whether it is still active, and what repair or monitoring is advised.
Phase six: weigh the proposals
Give each bidder the same report so the proposals answer the same question. Ask each one to spell out:
- the method and why it fits your foundation type;
- the count, type and location of piers, anchors, braces or injection points;
- drainage work included;
- excavation, backfill and restoring landscaping and interior finishes;
- which city permits the job needs, and who pulls them;
- what state license, if any, covers the work, and what the number is;
- proof of liability coverage and workers' compensation;
- the payment schedule, and warranty terms including transfer to a buyer.
Where one proposal calls for far more work than another, ask its author to explain the difference in writing.
Phase seven: through the work
Ask the crew where it will dig, drill or stage equipment, and clear those strips of patio furniture, planters and stored items. Walk through the rooms near the work with your phone and record walls, ceilings, floor tile and trim beforehand; stabilizing or lifting a foundation can open hairline cracks in finishes, and a before-and-after record settles who fixes what. Box up anything breakable on shelves along the affected walls. Confirm who requests utility locates, and set payments against finished stages rather than front-loading them.
Phase eight: the seasons after
Re-mark the old cracks once the crew leaves and keep up the same photo routine. Make a habit of looking at gutters, downspout extensions and grading after storms and wind. If a repaired crack opens again, or a door starts to stick in a pattern your earlier notes can't account for, write to the installer with dated pictures and keep a copy, while the warranty is still in force.
One file for the house
Store the baseline notebook, the evaluation, each proposal, the signed contract, permit records, invoices and the warranty together. A buyer's inspector is likely to ask about any foundation work, and a dated paper trail lets you answer clearly.
