A clean Official Alabama Wood Infestation Report means an inspector walked the accessible parts of a structure and did not see current, visible evidence of termite activity. It is not a statement about the condition of the decking under your floor, because nobody lifted the floor to look.
That distinction matters more in Alabama than almost anywhere else in the country, because every county in the state sits in termite infestation probability Zone 1 — the highest classification the U.S. Forest Service scale uses. “Very heavy” is not a description of one bad neighborhood. It is the whole state, coast to plateau.
What does the wood infestation report actually inspect?
The report is a visual, non-invasive inspection. An inspector examines exposed wood, foundation areas, and accessible crawl spaces or slab edges for signs of current termite activity — mud tubes, damaged wood, live insects. Nothing is opened up, and no flooring is removed to look underneath it.
That is the standard the inspection is built on, not a shortcut anyone is taking. Termite inspection protocols in Alabama, overseen by the Alabama Department of Agriculture and Industries, are visual by design because the report exists for a real estate closing timeline, not a renovation. It was never meant to certify what is under three layers of finished flooring, an underlayment, and a subfloor.
So when does anyone actually see the decking?
During a flooring job. That is the one point in the life of a house when the wood infestation report’s blind spot gets opened up — literally. Old flooring comes off, the subfloor is exposed, and whatever has or has not happened to it since the house was built becomes visible for the first time in years, sometimes decades.
This is not a scare story about a house that is secretly infested. Most subfloors that get opened up are simply old, and old is not the same thing as damaged. The point is narrower: a clean report from a real estate transaction five years ago tells you nothing about what a flooring crew will find when they pull up the carpet or the tile this year. The two events are unrelated in method and in timing.
Why does 2% weight loss matter to a piece of decking?
Because wood strength does not decline in proportion to how much wood has been lost. Research on decayed and infested wood shows that a loss of as little as 2% of a piece’s weight can reduce its strength by as much as half. A board can look mostly intact and still be a fraction of the load-bearing member it once was.
That is a structural fact, not a cosmetic one, and it is the reason the decking question belongs in a flooring quote rather than in an argument about how the floor looks. A sheet of subfloor can appear sound at a glance and still fail a load test. Nobody settles that by staring at it — it gets settled by opening it up, which is exactly what a flooring job does and a wood infestation report does not.
Where do Formosan termites change the picture?
Formosan subterranean termites are confirmed in at least a dozen Alabama counties, with the most documented activity concentrated in Mobile and Baldwin counties. They are more aggressive and build larger colonies than native subterranean termites, which is one more reason a five-year-old clean report tells a buyer less about current conditions than the paperwork implies.
Coastal counties carry a second variable that inland counties do not: water. Storm surge, wind-driven rain, and slow leaks all reach subfloors along the coast more often than they do farther north. On flooring recovery after water exposure, tile and rigid-core luxury vinyl plank typically come back if dried out properly, engineered wood sometimes survives depending on how long it stayed wet, and laminate and carpet essentially do not. The full breakdown of what recovers and what does not lives on the flood flooring hub.
How should the decking get handled in the quote, not the inspection?
The wood infestation report is not where subfloor condition gets settled — the flooring quote is. A quote that only prices the visible floor and skips the decking question is leaving the most expensive uncertainty in the project unaddressed until the crew is already mid-job.
A quote worth signing should specify, in writing:
- A per-sheet rate for replacing damaged subfloor decking, agreed before demolition starts
- Whether joist repair, if discovered, is in scope at all or handled as a separate change order
- Who has authority to approve additional work once the floor is opened — homeowner, contractor, or both in writing
- What a mid-project decking discovery does to the schedule, since sourcing matching subfloor material and drying time both take days, not hours
None of that is negotiable after the old floor is already off the site. It has to be settled while the quote is still a quote. The subfloor clause that belongs in every Alabama flooring contract is covered in detail on its own page, and it is worth reading before signing anything, not after.
What does this cost, if decking needs replacing?
Removing the old floor generally runs $1 to $4 per square foot, and that range is for taking up the existing surface — it does not include replacing subfloor decking underneath it, which is priced separately once the condition is known. There is no reliable flat number for decking replacement itself, because it depends on how many sheets are affected, whether joists are also compromised, and what the new flooring material requires as an underlayment.
These are planning ranges for budgeting a project, not a quote for any specific house — the final number depends on what the contractor finds and what the reader’s own project requires. For a figure tailored to a specific material and square footage, the cost estimator walks through the inputs that actually move the number, including the possibility of subfloor work, rather than guessing at one in advance.
Does the flooring material change the stakes?
Yes, in two separate ways: what the new floor needs from the subfloor underneath it, and how each material behaves if water or decay issues turn up later.
Solid hardwood and tile both demand a subfloor that is flat, sound, and properly fastened — neither forgives a soft spot the way a floating floor can. Luxury vinyl plank and laminate are more tolerant of minor subfloor imperfections but still require a stable base; neither should go down over decking that is structurally in question. Carpet is the most forgiving on subfloor flatness but the least recoverable if that subfloor ever got wet.
The full rundown of what each of the eight common flooring materials is good at, and where each one is the wrong answer for a room, is on the materials hub. None of the eight are termite-resistant or termite-proof, and no flooring material should be described that way — the subfloor question is about wood condition and structure, not about which surface goes on top of it.
Does the age of the house change what to expect?
Older homes have had more decades for something to happen to a subfloor, but age by itself is not a diagnosis. A house built in 1965 is not automatically a house with compromised decking, and a house built in 2005 is not automatically clear of it. What age changes is the odds a flooring crew is more likely to be the first people to look at that subfloor in a long time.
Birmingham’s housing stock has a median build year of 1965, with a quarter of homes built before 1940. Mobile’s median is 1975. Those numbers describe how old the wood generally is, not its condition — that is a separate question the quote needs to answer, not the year the house went up. A city-by-city look at build years and what that means for flooring jobs across Alabama is on the city hub.
Frequently asked questions
If a home just passed a termite inspection for a sale, is the subfloor fine?
A passing wood infestation report means no visible current activity was found during a visual, non-invasive inspection. It does not mean the subfloor was examined, because that inspection does not remove flooring to look underneath it. The subfloor question stays open until someone actually opens the floor.
Who decides if termite treatment is needed before flooring goes down?
That call belongs to a licensed pest control provider, not a flooring quote. If a flooring job uncovers something during demolition, the next step is verification by a qualified inspector, not a guess by whoever is on-site laying floor.
Does a flooring contractor need a permit to replace subfloor decking?
Permit requirements are set and enforced locally in Alabama, by each municipality or county, not by the state. Whether a given repair triggers a permit is a question for the reader’s own local building department before work starts. The hiring and permits archive covers what to ask a contractor about licensing and paperwork before signing.
What does the Alabama termite letter actually guarantee a buyer?
It documents what a visual inspection found on the day it was performed — nothing more, and nothing about future risk. The specifics of what the letter covers, and what it explicitly does not, are laid out on the termite letter coverage page.
The wood infestation report and the flooring quote answer two different questions, and confusing them is where cost surprises come from. The report says what an inspector saw from the outside on one day. The quote is where the reader and the contractor agree, in writing, what happens if the flooring job finds something the report never could have. The full context on the subfloor as the real issue behind any Alabama flooring job — termite zone classification, Formosan counties, and what “non-invasive” actually means — is on the termites and subfloor hub.
