The outside of a Vermont house takes a beating: long winters, freeze and thaw, snow sliding off steep roofs, and summers humid enough to keep paint and wood working. Windows, siding and gutters are where that shows. They are also where two Vermont rules hit a homeowner who might not expect either. One is a lead rule that treats old windows as a special case. The other is a pot of public money for weatherization that is unusually generous through the end of 2026.
Why a pre-1978 window replacement is never a small job here
The Health Department's renovation, repair and painting rules set size thresholds for most work in older houses: a square foot of painted surface in an interior room, or, outside, more than twenty square feet on any single wall of a home its owner lives in, before lead-safe practices kick in. Windows are the exception. In a house built before 1978, replacing a window is always RRPM work, no matter how small the window or how little paint is disturbed.
The reason is how old windows fail: painted sashes grind against painted jambs every time they open, and the dust collects on sills and floors. Taking one out disturbs exactly that. So the contractor who replaces windows in your old house in St. Albans or Brattleboro must work under an RRPM license, with containment and cleanup to match. Ask for the license, and ask what the setup looks like inside and out.
Siding and trim follow the regular rules. Scraping or removing painted clapboards on a single side of an owner-occupied house becomes lead-safe work once it passes twenty square feet, which any real siding job does. For a rental, the exterior threshold drops to one square foot per side.
Using the 2026 weatherization incentives before they run out
Efficiency Vermont's 2026 rebate announcement offers up to 90 percent cash back on weatherization, with richer terms for households with lower and middle incomes; the offer runs until the money is gone or the year ends, whichever comes first. That covers air sealing and insulation rather than new windows, but the two often go together: a contractor replacing siding has the walls open, and that is the cheapest moment to insulate them.
If your exterior job is partly about comfort and heating bills, ask whether the contractor works with Efficiency Vermont's program, or whether you should get a separate weatherization contractor in before the siding goes back on. Air sealing is often the better first dollar.
Burlington's rental sale rule and what it means for your windows
Burlington has an older weatherization rule of its own. Under the city's Time of Sale Energy Efficiency Ordinance, passed by the City Council in March 1997, when a building containing tenant-heated rental units sells, those units have to be weatherized. The required spending is capped at 3 percent of the sale price or $1,300 per unit. If you are buying or selling a rental in the city, an exterior contractor may be part of meeting it; ask Burlington Electric which measures count before you hire.
Permits for windows and siding in Burlington and elsewhere
In Burlington, windows, roofing, siding, fences and decks are handled on short-form applications through the Department of Permitting and Inspections. Storm doors and storm windows are exempt from the building permit, as are in-kind repairs of $1,000 or less. Zoning approval comes first, and in an older neighborhood that is where a change of window style or siding material gets looked at.
Outside Burlington, the usual answer is a town zoning permit or nothing. A window contractor in Morristown or Hyde Park should know their own towns; if you are in a village with a design review district, call the zoning administrator before you choose a window.
Siding a lake camp within 250 feet of the water
Vermont protects the land near its lakes. Under 10 V.S.A. § 1442, the area within 250 feet of any lake larger than 10 acres is Protected Shoreland Area. New development, redevelopment or clearing of vegetation in that band may need a shoreland permit from the Department of Environmental Conservation, under rules the DEC lakes permit page explains.
Replacing siding on a camp in Grand Isle, Alburgh or on Lake Memphremagog in Newport is usually maintenance. But a job that grows into a new porch, an enlarged footprint or cleared trees for staging can cross into permit territory. Ask the contractor whether they have worked in the shoreland band before, and call DEC if the scope includes anything new on the ground.
Restoring old sashes instead of replacing them
Not every old window needs to go. A wood sash from a house built in 1900, given new glazing putty, weatherstripping and a tight storm window, can keep working for a long time. Some exterior contractors restore windows; most replace them. Ask which the contractor does, and if you want restoration priced, ask for it as a separate line.
The lead rule does not care which you choose. Stripping and reglazing a painted sash in a pre-1978 house disturbs the same paint as taking it out, and the work still needs an RRPM-licensed crew, whether it happens on site or in a shop. Ask where the sashes go while they are being restored, and how the openings are closed up in the meantime, especially in a Derby or Westminster house in October.
Ladders, staging and the insurance behind them
Exterior work is work at height. A siding crew on a three-story house in Colchester spends days on staging, and an accident on your property is a question for their insurance, not yours, only if they carry it. A contractor registered under chapter 106 must carry liability insurance of $1,000,000 for each occurrence and $2,000,000 overall. Request a certificate naming you as holder, and ask separately whether the crew is covered by workers' compensation. If the answer to either is vague, keep looking.
Reading an exterior quote
Gutters are a judgment call in snow country. Snow and ice sliding off a steep roof can strip a gutter in one storm, and some owners decide they are not worth it. Where they make sense, over an entry or a deck, the questions are how they are hung, where they sit relative to the slide, and where the downspouts discharge. Water dumped next to the foundation in a spring thaw ends up in the basement.
The Vermont calculator default for a typical exterior job is about $3,500 to $9,700; the Vermont exterior cost page separates windows, siding and gutters. Above $10,000, the contractor must be registered with the Office of Professional Regulation, which you can check on the OPR lookup, and must give you a written contract with dates and a price basis. For windows, the quote should name the product line, the glass package and how the old frames are handled; for siding, the material, the trim, the house wrap and what happens to rotted sheathing found underneath. A contractor in Essex or Putney who writes all of that down is one you can hold to it.
