Read more →National chains lure you with $99 ‘sweeps’ that often skip full inspections, leave behind dust clouds, and use untrained crews. Silas Chimney’s $225–$450 pricing reflects a white-glove process: camera inspections, hand-brushing flues, HEPA vacuuming, and a 100% satisfaction guarantee. We don’t cut corners—we restore your chimney to code, which saves you thousands in future repairs.
Most Waltham homes require 90–120 minutes for a full sweep and Level 2 inspection. Unlike chains that rush through 5 jobs a day, we block 2-hour windows to ensure no detail is missed. If your chimney has heavy creosote or masonry repairs, we’ll call you upfront with a time estimate—no surprises.
A basic sweep removes soot; a Waltham-level inspection uses 4K cameras to check for cracks, blockages, or deteriorating liners—even in hard-to-reach offsets. We document findings with photos and provide a written report, meeting Massachusetts code 2111.1. Chains often skip this; we make it standard.
Absolutely. Our non-toxic cleaning agents dry within 30 minutes, and we test draft performance before leaving. Unlike some sweeps that recommend waiting 24 hours, we ensure your fireplace is safe to use immediately—just light a small test fire to confirm.
New England’s freeze-thaw cycles trap moisture in chimneys, accelerating creosote buildup and liner cracks. Waltham’s humidity and wood-burning culture demand annual sweeps—more if you use softwoods like pine. Skipping this risks chimney fires or carbon monoxide leaks.
A decade of neglect can hide a 1/8-inch creosote glaze—enough to ignite at 1,000°F. In Waltham, where many homes predate 1950, original masonry often cracks under pressure. Our inspections catch these flaws before they become emergencies, saving you from costly rebuilds.
Yes. Our 1-year workmanship guarantee covers repairs to flues, liners, and caps—even damage from Waltham’s notorious squirrel infestations or ice dams. We document pre-existing conditions with photos to ensure your claim is honored.
A clean exterior doesn’t mean safety. Creosote hides behind flue tiles, and cracks in Waltham’s older chimneys often lurk unseen. We use cameras to inspect every inch, because ‘looks clean’ isn’t the same as ‘code-compliant.’
