Boston odors, gone for good.

Yes. We have a team in the Boston area covering Newton, Wellesley, Needham, Lexington, Belmont, Arlington, Winchester, Andover, Natick, Dedham, Westwood, Milton, Braintree, Weymouth, Hingham and the city neighborhoods around them, and same or next day is normally realistic. Tell us the ZIP and the type of property when we call you back and we will confirm a time. The work carries our 100% guarantee.

Usually, yes, once any leak is fixed. Heating oil soaks into concrete, stone and anything stored nearby, and that is what keeps smelling after the drip is gone. We treat the materials holding it and seal what needs sealing. If the tank or the burner is still leaking, have your oil company fix that first, or the smell simply comes back.

Call before you unpack if you can, because an empty apartment lets us reach the floors, closets, radiators and vents. Smoke and pet odor are the two most common, and both are fixable at the source rather than covered up. Most apartments take one to four hours.

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.

Same or next day is normal in Greater Boston 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.

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.

It is one of the most common reasons people call us, and the timing that works is after the clear-out and before the photographs. Smell is the first thing a buyer registers, before they have looked at a single room, and it is the objection nobody talks themselves out of afterwards. It is also the one thing a viewer will not raise with your agent, so you tend to find out through the offers rather than the feedback. We treat the source so the house reads as clean rather than heavily scented, because buyers are wise to a house that smells strongly of anything, including air freshener. Agents in Greater Boston tend to be blunt about this, and they are usually right.
