Most excavators in Maine park the machines in December and tell you to call back in May. We don’t. We lay electric ground-thaw mats over the dig, give them about three days to drive the frost out, and then dig it the same way we would in July. Your septic gets fixed in January instead of after mud season.
That is exactly what this setup is for. A failed septic in February is not a spring problem — it is a right-now problem, and we own the mats and the machines, so we aren’t waiting on a rental yard to fit you in. We are in Dover-Foxcroft and we will travel anywhere in Maine for winter work. Call and we will tell you honestly how fast we can be there.
This is the part almost everybody gets wrong, and it is why most people assume winter digging can’t be done.
Frost is a crust. Below the frost line the ground never froze at all — it sat there at about 45°F all winter, same as it does under your house.
The mats only have to beat the crust. Once the bucket is through it, the excavator is working normal ground the rest of the way down.
That is the whole trick. An eight-foot septic hole doesn’t need eight feet of thawing — it needs about two. Everybody assumes you would have to melt the entire excavation, decides that’s absurd, and puts the job off until May. You don’t have to.
Six steps. The only one that takes real patience is the waiting.
The dig area, how we get a machine to it, and where the power for the mats comes from. No power at the site is fine — we bring a generator. We sort all of it out before we quote you, so there are no surprises in either direction.
The mats have to sit on dirt, not on snow — snow is insulation, and it would hold the heat off the ground instead of letting it in. So we scrape the footprint clean the day we start, carefully, because there is sod under there we would rather not tear up.
Electric ground-thaw mats laid over the exact footprint — long strips for a trench, squares for a tank hole. Staked down and covered so the heat goes into the ground instead of the sky.
The mats push the frost out from the top down. How long depends on how cold it has been, how much snow was on it, and what the soil is. We will give you a real number after we see it.
Mats come up, excavator goes in. From here it runs like any other job — tank set, line run, footing cut, trench opened.
Same standard we hold in August. Before we pull out we grade it back, put grass seed down and cover it with straw. It sits through the cold and comes up on its own the moment the soil warms — so the ground is already working for you in spring instead of waiting on us to come back.
Backing up, collapsed lid, cracked tank, saturated field. This is the call we set the winter operation up for in the first place.
A line that froze because it was never deep enough, or one that let go. We open it, fix it, and bury it at a depth that won’t do it again.
Broken, crushed or root-blocked line between the house and the system.
Power, water and conduit. A new electrical entrance doesn’t have to wait for spring — we trenched one for a client last winter.
The line between the house and the tank, or the tank and the field. Crushed, cracked, frozen or root-blocked — we open it, fix it and put it back at a depth that holds.
A saturated or failed field doesn’t get better on its own, and it doesn’t have to wait for May either.
Snow is insulation. Ground that has sat under undisturbed snow all winter freezes noticeably shallower than ground that has been plowed or driven on bare — the same reason frost runs deeper under a scraped driveway than under the lawn beside it. Less frost means fewer thaw days, and fewer thaw days means less on your bill.
So if a job is already planned, leave the snow alone on the patch we are going to dig. Not your driveway — keep that clear, we have to get a machine in there. Just the dig itself. We will scrape it off the morning the mats go down, by which point it has already done its work.
None of this applies if something just failed. Call us and we will deal with whatever is on the ground when we get there.
Including the ones most contractors get vague about.
Yes, some — and we will show you exactly where.
Two things move. Our hours are higher in winter — $250 rather than our summer rate — because the daylight is short, the cold is hard on machines and on people, and there is a thaw to set up and look after before anybody digs. And the ground-thaw setup itself is a line on the quote.
What does not move is the material. A tank is a tank, a leach field is a leach field, and pipe, stone and gravel cost what they cost in January. On a job of any real size that is the bulk of the bill — so the winter premium lands on part of what you are paying, not all of it.
What you get for it is the job finished in February instead of sitting on a spring waiting list behind everybody else who also put it off. And for a failed septic or a broken water line, waiting was never really an option.
Then we bring a big generator. It is not a problem, and it does not stop the job.
That comes up more than you would think around here — a camp that is shut off for the winter, a lot with no service run to it yet, a dig too far from the house to reach. We run the generator through the thaw days and the mats never know the difference.
The mats do pull real power — one 5′×9′ mat is about 14 amps, which is a whole outdoor circuit for a single mat — so on a tank hole or a long trench we normally bring the generator anyway rather than ask your house to carry it. If there is serviceable power sitting right next to the dig we will use it instead and knock it off the price.
Either way it is our problem to solve, not yours, and it is a small line on the bill. The money in a winter job goes where it goes in a summer job — into the digging and the fixing.
The mats themselves will not. They sit on top of the ground, they don’t dig, and they don’t scorch anything — you can grow grass there the next summer.
The excavator is a different conversation. Thawed winter ground is wet ground, and a machine working on wet ground leaves ruts. On an emergency job we accept that, because a septic backing up into your basement outranks a lawn. Anyone who promises you a winter dig with no marks on the lawn is selling you something, and we will tell you what it is likely to look like before we start.
What we do about it: before we leave we grade the disturbed ground back, seed it and cover it with straw. That is dormant seeding — the seed lies there through the rest of the winter and germinates by itself as soon as the soil comes up to temperature, and the straw keeps it from washing away in the melt. You are not looking at bare dirt all spring, and you are not waiting on us to come back and start the job over.
Yes — because it isn’t frozen solid. It is frozen down to somewhere between one and three and a half feet, and unfrozen underneath that. We thaw the frozen part and dig through the rest. Ground-thaw mats are standard equipment on commercial work in cold climates; there is nothing experimental about it.
We clear the snow off the dig area and lay the mats the same day we arrive. From there, plan on about three days of thawing before we can dig, then the dig itself, which runs about the same as it would in summer. We are not going to promise you an exact number of hours before we have looked at it — how cold it has been, how much snow was on the ground, and what the soil is will all move it.
Call Matthew at 207-343-7560 and we will tell you straight away what we can do and how fast. Repairs and tank replacements on an existing system are the bread and butter of our winter work.
A brand-new system is different: it needs a soil test and a state-approved design from a licensed Site Evaluator before anybody puts a bucket in the ground. If that is what you are looking at, call us in the fall and we will get the testing and the paperwork lined up before the ground closes up.
No. The excavator, the skid steer, the dump truck and the mats are ours. In an emergency that is the entire difference between coming Thursday and coming whenever the rental yard has something free.
The whole state. We are based in Dover-Foxcroft and Piscataquis County is our back yard, but we will travel anywhere in Maine for winter work — and in winter there are not many outfits that will come at all, so we get calls from a long way off.
The mobilization figure below covers our regular working area. If you are a long haul from Dover-Foxcroft we will quote the travel honestly up front rather than bury it, and we will tell you plainly if we think somebody closer to you can get to you sooner.
These are winter hours, and they are higher than our summer hours on purpose — short daylight, hard cold on the machines and the crew, and a thaw to set up and tend before anybody digs. Outside the frozen months our rates come back down. We would rather show you two honest numbers than one average one.
Tell us what is wrong and where it is. We will tell you honestly whether it can be done now.
