Extera Works

Extera Works is a two-person exterior specialty shop on Cape Cod, run on-site by partners Vlad and Dzmitry, that has built a fast, consistent reputation this year installing cedar shingle siding and custom copper work — gutters, flashing, chimney caps. It works Cape Cod and the South Shore. The through-line across 23 five-star Google reviews, all from 2026, is precision on the small stuff: reviewers keep pointing to straight corners, uniform shingle flares, and trim lines that line up rather than a vague "the siding looks nice". One homeowner adding onto an existing house says the new section "doesn't look patched together" and that neighbors have asked if it was original construction. Another, replacing siding on a tight lot right next to a fence, said the crew was cleaner and more careful than expected and left the fence untouched. The copper side of the business shows up too — custom-fabricated chimney caps built to keep osprey from nesting, drone footage sent during the job, and a roof replacement finished on time and on budget. Recent activity is heavy — 20 of the 23 reviews landed in the last six months — and nothing negative appears anywhere in the record. Several jobs are pool houses and new-construction exteriors, alongside straightforward siding replacements on existing homes; one reviewer found them through a friend's recommendation after being wary of contractors who "say they do siding" but leave uneven lines a year later. There isn't a documented downside to flag. The record is short — every review dates to 2026 — but it's unusually specific and heavily referral-driven, which says something about word of mouth around Cape Cod even this early. Worth calling for cedar shingle siding, custom copper gutters and flashing, or copper roof work — the trim-and-corner detail work is what customers single out, and it's the two partners themselves running the jobs.
