Masonry & Roofing Contractors in Andover: what to know
Snow load, frost depth and stone
The higher ground of Tolland County gets a longer, colder winter than the shoreline, and it shows in the work. Snow accumulates on roofs and stays there, which drives ice dams wherever an attic leaks heat. Frost drives deeper into the ground, which is why footings and retaining wall bases around Andover have to go below frost depth or they will heave. And the freeze-thaw count, the number of times a year that water in a mortar joint freezes and expands, is higher here than anywhere on the coast. Every one of those cycles opens a joint fractionally wider.
The terrain also means stonework is everywhere: fieldstone foundations, dry-laid walls along old property lines, stone steps and terraces cut into slopes. Much of it is a century or more old and worth restoring properly. A mason who works with stone around Andover should be able to tell you which stones are still sound, whether a wall needs resetting or full rebuilding, and what the drainage behind it should look like.
Reading the condition of your masonry
You can learn a lot about a Andover building from the ground. Run a key along a mortar joint: if it scratches out as sand, the joint is spent and the wall is taking on water. Look for joints recessed more than a few millimetres behind the face of the brick: that is a joint no longer shedding water. Look for the white bloom of efflorescence, which means water is moving through the masonry and carrying salts out with it. Look for brick faces that have popped off, exposing the softer core; that is usually the signature of frost, of a hard repointing mix, or both.
On a chimney, look at the crown from a window or with binoculars. Cracks radiating from the flue, a crown flush with the brick instead of overhanging it, and a missing flue cap are the three things that account for most chimney leaks in Connecticut.
Getting the roof detail right
Anyone quoting a re-roof on a Andover property should be talking about more than shingles. Ask about the ice and water membrane at the eaves and in the valleys, the backstop for when an ice dam forms anyway. Ask about ventilation: balanced intake at the soffit and exhaust at the ridge keeps the deck cold and the shingles from cooking from below. Ask what happens to the chimney flashing and the vent boots, which is where the next leak will otherwise come from. And ask what happens if the deck turns out to be soft once the old covering is off, and at what price per sheet.
A quote that lists only a shingle brand and a total price is not a specification, and it makes comparing two contractors around Andover impossible.
Checking out a Connecticut contractor
Contractors performing home improvement work on existing Connecticut homes are generally required to hold a Home Improvement Contractor registration with the state Department of Consumer Protection, and you can look up a registration yourself before signing anything. Connecticut also requires certain home improvement contracts to be in writing with specified terms, and maintains a Home Improvement Guaranty Fund that may help homeowners in defined circumstances, check DCP for the current requirements and eligibility rules rather than relying on what a salesperson tells you.
Beyond registration, ask any Andover contractor for a certificate of insurance sent directly from their insurer, a written scope that names materials and methods rather than just a total, and references for masonry work of the same type and age. Do not pay in full up front.
