Yonkers odors, gone for good.

Yes, both. In apartment buildings we look at how the smell is traveling between units as well as what is in your own space, and we can treat a single unit, a hallway or a garbage room. In houses the usual culprits are basements, closets and floors, and we go to the source in each.

Yes. We use green, non-toxic methods, including hydroxyl generators that are safe to run in occupied rooms, and we never use ozone or chlorine. Most homes can be lived in normally during or straight after the work.

Same or next day is normal in Yonkers and lower Westchester rather than a best case. If you call in the morning with something small there is a reasonable chance of that afternoon. What we will not do is take the booking and then push you back twice, so if the day is genuinely full we will tell you the next real slot when you call. Give us the ZIP and the type of property and we will pin a time down rather than say we will be in touch.

That is the most common call we get, and it is not bad workmanship. Smoke residue is not on the surface, it is in it. Tar and nicotine condense out of warm air and work into plaster, drywall paper, timber, carpet backing and the inside of the ductwork, so a heavy clean and two coats buy you a few weeks and the first warm humid day brings it back through. Sealing does have a place, but only after the residue underneath has been dealt with and only on surfaces that genuinely cannot be treated. Doing it in the wrong order is the most expensive mistake we see, because the paint has to come off again before anyone can get at the problem.

If the smell comes back within 7 days of your treatment, we come back and fix it, and you do not pay twice. That is the whole of the guarantee, and it is deliberately short and plain. The reason we can offer it is that we treat the source instead of covering it, so there is usually nothing left to come back. Where a smell does return, it is almost always because something is still feeding it: water still getting in, a drain still open to the sewer, an animal still in the wall. In that situation we will tell you what needs fixing first rather than keep re-treating a symptom and billing you for it.

Because by the time a room smells, the urine is almost never still in the carpet. It has gone through the backing, through the underlay and into the subfloor, and in an older house it will have found the gaps between the boards. Cleaning the carpet treats the layer holding the least of it. Urine also crystallizes as it dries, which is why the smell surges on a humid day and fades on a dry one, and why steam cleaning can briefly make it worse: you have just added moisture to the salts. We work out how far it went before deciding what to treat, and sometimes that means lifting a section of carpet to look. Knowing is cheaper than guessing.

We quote per job rather than publishing a rate, because the same smell in two houses is not the same job. What moves the price is how far the odor has travelled, not how bad it smells on the day. Cigarette smoke that has been in a house for years has gone into drywall, carpet backing and the inside of the ductwork, and that is a different piece of work to the same smell in a rental that was smoked in for one winter. Tell us the room count, the odor, and roughly how long it has been there, and we will call you back with a real number rather than a range that means nothing. The quote is free and there is no charge for a visit that turns into advice rather than work.

No, though it is common enough that people accept it. A musty smell is the by-product of organic material staying wet: untreated timber, cardboard boxes, old carpet, drywall that wicked up water once and never fully dried. It is worse in summer because warm humid air meets cool basement surfaces and condenses on them, which is the opposite of what most people expect. Before treating anything it is worth knowing whether the space is actively wet or only humid, because they need different answers. Active water is a drainage or sump problem and has to be fixed first. We will not tell you a treatment fixes a leak, and if water is still getting in we will say so before you spend money rather than after.
