Old foundation movement, and movement that is still happening
Owners usually arrive with one alarming word from an inspection report and no sense of the scale behind it. The term covers everything from a hairline crack you could reasonably ignore for another twenty years to a wall that needs excavating and rebuilding.
What we look for is whether the movement has finished. Old cracks with clean, dry, unchanged edges tell a different story than fresh ones with fine grit at the base. Neither answer stops us buying. It changes what the foundation work costs, and we would rather know than guess.
How we help Commack owners with foundation problems
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 Commack 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 Commack market underneath this
The median is up 7.69% year over year as of 2026-05. A firming market gives you a little room for error on price, which is worth more than it sounds when the house is not in showable condition. At a $840,000 median, Commack buyers are paying enough that they expect the house to be finished. A dated kitchen is a deduction in a cheaper market and close to disqualifying in this one, which is why unrenovated houses here sit while the renovated ones move. The median house here goes under contract in about 29 days, which is quick for Long Island. It is also a figure that only applies to property in showable condition.

Where a financed sale comes apart over the foundation
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 a Commack 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
An engineer report is worth having when you are deciding what to do with the house. It is not something you should be buying in order to sell it.
We price foundation problems from what we can see, from what caused the movement, and from having put right a great many of them. Where the picture is genuinely unclear we bring an engineer in at our own cost. Carrying that expense is part of what an experienced buyer is for, and it is one of the reasons a foundation does not slow us down.
How we arrive at a number on a house with foundation problems
The honest answer on a house with foundation problems is that we work backwards from what it is worth once it is fixed, subtract what fixing it costs, and subtract what we need to make for the risk of being wrong about either. There is no secret to it and no algorithm.
- What it is worth repaired. Not the Commack median of $840,000 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 Commack the stock is largely colonial and split-level, and on houses that age the mechanicals are usually the expensive part rather than the cosmetics.
- How long we will hold it. The median Commack house goes under contract in about 29 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. Opening a wall finds things. That risk is priced in, which is a large part of why a cash number sits below a retail number.
Why the number works for us and not for you
This is the part most cash buyers are vague about, so here it is plainly. We run millions of dollars of construction a year. That volume buys materials at contractor pricing and keeps the same crews working year round, which means the identical renovation costs us roughly half what a homeowner would pay to have it done.
That gap is the business. It is also why doing the work yourself before selling so rarely pays: you would be buying the same roof and the same boiler at retail, then hoping the market hands it back to you at resale. It usually does not. We are not making money because you sold cheaply. We are making it because we build cheaply.
And if the number does not work for you, say so. We would rather hear that than talk anyone into anything. We will look at your situation and tell you honestly what we think your options are, including the ones that do not involve us. Plenty of people are better off listing with an agent, and when you are one of them we will say so rather than let you find out later.
What foundation problems do to your pool of Commack buyers
Most sellers who call us about foundation problems have already lost one contract over it, sometimes two. There is nothing unusual in that and it says very little about the house.
What it says is that the retail market cannot carry structural risk. A family buying a home to live in has one pot of savings and no appetite for an unknown, so they walk, and every walk costs you weeks and a little more of the asking price. A foundation does not get cheaper while a house sits, so reaching the end of that road sooner is worth a great deal.
How selling a house with foundation problems in Commack works
- 1
Start with the basics
Where the house is (11725) and a rough sense of its condition is all we need to begin. Call or use the form. Nothing needs fixing or clearing out beforehand.
- 2
We walk through it once
A single visit by one person, normally under thirty minutes. With a colonial or split-level built when most of Commack was, the roof, heating and electric matter far more to us than the kitchen does.
- 3
You see the number
Within a day you get our offer as one written figure. Get a Suffolk County agent's opinion alongside it if that helps. For a house that could go on the market as it stands, listing may come out ahead, and we will tell you if so.
- 4
Closing happens on your date
If you need it done quickly, it can be. If probate, a tenant or a move means waiting, we wait. What you skip is the 74 to 89 days a Commack listing usually spends on finding a buyer and then on that buyer's lender.
Foundation problems in older Commack houses
Water is behind most of it. Ground that stays saturated presses on a block wall differently than dry ground does, and gutters that discharge against the house have been quietly loading the foundation for decades.
So we look outside before we look in. Where the grading falls, where the leaders let go, whether a neighbor's driveway sends water your way. Repairing a wall while the water that moved it keeps arriving is how people end up paying for the same job twice.
Common questions
Do I need a foundation engineer's report before you will look at a Commack 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 Commack sale over the foundation. Can you still buy?
Yes. A financed sale falling apart tells us about the lender, not about your house. We can pick the Commack purchase up from wherever the last one collapsed.
Will foundation problems ruin my offer price?
They affect the number the way any real repair does, because the work has a genuine cost. What they do not do is end the conversation. We would rather price the foundation accurately once than be vague now and revise on you later.
Should I repair the foundation before selling my Commack 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.
