Old foundation movement, and movement that is still happening
There is a genuine difference between a house that has settled and a house that is failing, and nobody should have to work that out alone from a photograph on a phone.
We look at the grading outside, the gutters, and where the water goes when it rains hard, then at the foundation itself. Plenty of houses here sit on block rather than poured concrete, and block behaves differently when the ground around it stays wet for months. Which one you have changes what foundation problems mean for your house and for your price.
What we bring to a foundation problem, beyond the money
Buying the house is the part everyone understands. It is rarely the whole of what somebody in this position needs.
We have been buying and repairing houses on Long Island for 15+ years, so we know the structural engineers worth calling and the contractors who do foundation work themselves rather than farming it out. We will bring them in whether or not the Uniondale house ends up being ours. Describe the crack, tell us where it sits, and we will tell you what kind of foundation problem it is likely to be.
The Uniondale market underneath this
The median has slipped 1.95% year over year as of 2026-10. It is a small move, but a softening market punishes the houses that need work first - buyers with choices do not choose the project. At a $684,649 median, Uniondale is a market where buyers expect to do some work. That helps a seller with a dated house and hurts one with a genuinely broken one, because the pool that will take on a project is not the same pool that will take on a gut. Houses here take a median of 50 days to go from listed to under contract, and that clock only starts once the property is ready to show.
Uniondale is roughly 32,473 people in Nassau County, ZIP 11553, and the housing stock is mostly cape cod, colonial, ranch. Around Hempstead Turnpike and the Nassau Coliseum, most of it is old enough that the mechanicals are on their second or third life. We have been buying across Nassau County for 15+ years. We know what the Uniondale Union Free School District does to a resale price, which blocks still have oil tanks in the ground, and what a house like yours is actually worth here.
Why a lender will not finance a house with foundation problems
Sellers often discover the financing problem late, after a contract is signed and the inspection has happened, which is the most expensive moment to find out.
What follows is a request for an engineer's report, then a request that the foundation repair be done before closing, then a renegotiation, and frequently a buyer who withdraws regardless. Each round of that puts an Uniondale house back on the market with more days on it and a story attached to it.
You do not need a foundation engineer report to sell to us
Do not spend money on a structural engineer on our account. If a report is needed, we order it and we pay for it.
Sellers often assume they have to arrive with documentation before anyone will take them seriously. You do not. Tell us what you can see, let us look once, and if the foundation warrants an engineer we will bring one out ourselves. If you already have a report from a sale that fell apart, show us and it saves everyone a step.
How we arrive at a number on a house with foundation problems
On a house with foundation problems we start from the end: what it sells for once the work is done. From that we take away the cost of the work and a margin for the chance that we have misjudged either one. That is the whole method. Nothing is hidden in it.
- What it is worth repaired. Not the Uniondale median of $684,649 on its own, but what houses like yours on your street actually closed at recently.
- What the work costs. Roof, boiler, electric, the kitchen and bath. In Uniondale the stock is largely cape cod and colonial, and on houses that age the mechanicals are usually the expensive part rather than the cosmetics.
- How long we will hold it. The median Uniondale house goes under contract in about 50 days once it is showable, then waits 45 to 60 days more on the buyer's lender. Ours has to get to showable first, and we carry taxes and insurance across the whole of it.
- What we are wrong about. Walls and floors hide things until they come up. We price for that uncertainty, and it accounts for much of the distance between a cash offer and a retail price.
How we can pay this and still make it work
Most cash buyers skip this part. We do not. We run millions of dollars of construction a year, so we buy materials at contractor prices and keep our crews busy all year. The same renovation costs us roughly half of what you would be quoted as a homeowner.
That difference is how we make money. It is also why renovating before you sell seldom comes out ahead: you would pay retail for the roof and the boiler and then hope a buyer pays you back for them. Most of the time they do not. Our margin comes from building for less, not from buying from you for less.
If our number does not work for you, tell us. We would much rather hear it than push. We will go through your situation and give you a straight view of your options, including the ones that leave us out. A lot of people do better listing with an agent, and if you are one of them we will tell you now rather than have you find out later.
Who buys a house with foundation problems, and what they pay
Two things have to survive for a listed sale to close: the buyer's nerve and the buyer's lender. A foundation finding tends to take out both.
The buyer reads a report full of phrases like differential settlement and lateral movement and cannot tell whether it means a weekend of work or a catastrophe. The lender starts asking for engineering documentation. Either one alone ends the contract, and the house goes back on the market in Uniondale looking staler than it did before.
How selling a house with foundation problems in Uniondale works
- 1
You tell us about the house
An address in 11553 and a rough idea of condition. Two minutes on the phone or the form. We do not need photographs, a clean house, or anything fixed first.
- 2
A quick look in person
We visit once and it rarely takes more than half an hour. On the cape cod or colonial houses that make up most of Uniondale, we check the roof, the boiler and the electric before anything cosmetic.
- 3
We put a figure in writing
You have a written number within 24 hours, a single figure rather than a "somewhere around". Feel free to check it with a Nassau County agent. When a house is ready to list as it is, listing can beat us, and we would rather you knew.
- 4
You choose when to close
Soon, or months away if probate, a tenant or your next move has to come first. You also avoid the 95 to 110 days a listed Uniondale house typically takes to find a buyer and get through the buyer's mortgage.
Crawl spaces, block foundations and Uniondale additions that moved
A great many houses here went up in the postwar decades and the footings reflect it. Block walls, shallow crawl spaces, slabs poured over fill, and additions built later on footings that were never tied into the original.
That last one accounts for a fair share of what gets called a foundation problem. A rear extension settles at its own rate, the joint between old and new opens up, and the inside of the house tells on it through cracked ceilings and a door that will not latch.
Common questions
Do I need a foundation engineer's report before you will look at an Uniondale house?
No. If a report on the foundation is needed, we order it and pay for it ourselves. Bring whatever you already have, including anything from a sale that fell through, and we will work from that.
Is the crack in my basement settlement or a foundation problem?
That is not a question to settle from a photograph alone. What we can do is walk it with you, say plainly which category it looks like, and bring an engineer in if the answer matters to what you decide next.
A buyer's lender killed our last Uniondale sale over the foundation. Can you still buy?
Yes, and that is the usual route to this conversation. We buy with our own funds, so there is no lender to satisfy and no repair required before closing.
Will foundation problems ruin my offer price?
It changes the figure, not the willingness. Because we do this work at contractor pricing, the deduction is often smaller than the quotes homeowners get handed.
Should I repair the foundation before selling my Uniondale house?
Sometimes that genuinely is the better route, and we will say so if we think it. The risk is paying for the work, then having a fresh inspection turn up something else and losing the buyer regardless.
