Every chimney problem has a specific fix. We don't sell you a full rebuild when a crown repair will do. Here's what we handle:
Creosote is the primary cause of chimney fires. It builds up every time you burn wood, and a single flue fire can reach 2,000°F. We remove stage 1, 2, and 3 creosote deposits using rotary brushes and commercial vacuums that keep soot out of your home. Most sweep jobs take 60 to 90 minutes. Learn more about chimney cleaning in Dallas or read the creosote warning signs you can spot from your living room.
Annual inspections catch problems before they become expensive. We offer both Level 1 and Level 2 inspections. A Level 1 covers accessible parts of the system. A Level 2 includes video scanning of the flue interior and is required when you sell or buy a home. See the difference in our guide on L1 vs L2 chimney inspection for Dallas homes, or check the 2026 chimney inspection cost guide.
Lewisville's heat cycles accelerate mortar deterioration. North Texas summers regularly top 100°F, and that thermal expansion cracks joints faster than in cooler climates. We handle crown repairs, tuckpointing, flashing repair, and liner replacement. Read what to expect during masonry chimney repair in Dallas and learn about how long chimney crown repair in Dallas takes.
Not every damaged chimney needs a full tear-down. Sometimes only the section above the roofline has failed. We assess whether a partial or full rebuild makes sense before any work begins. Check out partial vs full chimney rebuild: which fix fits your Dallas home or visit our chimney rebuilding Dallas page.
An insert turns an inefficient open hearth into a real heat source. Gas inserts require a properly sized liner; wood-burning inserts need clearance checks and a sweep before installation. We handle the full process. See our nearby fireplace insert installation in Frisco, TX page for details on what the process involves.
Water is the number one enemy of brick chimneys in North Texas. Summer thunderstorms drive moisture into hairline cracks; freeze-thaw cycles in January widen them. We apply professional-grade sealers and can replace deteriorated clay liners with stainless steel. Read our guide on clay liner vs stainless for Dallas homeowners and the 2026 chimney waterproofing cost guide.

Safe Flue Chimney Sweep And Repair provides full-service chimney and fireplace work across Lewisville, TX, operating out of our Dallas base. We work in neighborhoods throughout Lewisville, from the established homes near Old Town Lewisville to newer construction in Castle Hills and properties along the Lake Lewisville waterfront where humidity and wind exposure accelerate masonry wear.
Many homes in Lewisville were built in the 1980s and 1990s during the area's rapid growth period. Chimneys from that era often have clay tile liners that are now reaching the end of their service life. A crack in a clay tile is not visible without a camera inspection, but it can allow heat and combustion gases to reach adjacent framing.
We explain what we find in plain language and give you options, not pressure. If a $300 repair fixes the problem, that's what we recommend. If a rebuild is genuinely necessary, we show you why with photos or video from the inspection.
Gas fireplaces need attention too. Many homeowners assume a gas unit is maintenance-free, but the burner ports, pilot assembly, and venting all require periodic inspection. We service both wood-burning and gas systems. Read our breakdown of how often to clean a chimney for wood-burning vs gas fireplaces in Dallas.

Chimney problems don't announce themselves. Most go undetected for years because the damage is inside the flue where nobody looks. North Texas conditions make the timeline shorter than homeowners expect.
Mortar joints in North Texas clay expand and contract up to 15 times a year due to summer heat and winter cold swings. That movement cracks joints that then absorb water from the storms that roll through Lewisville off Lake Lewisville every spring and fall.

These are the questions we actually get on calls from homeowners in Lewisville, Castle Hills, and around Lake Lewisville.
☎ (214) 441-6336For a wood-burning fireplace used regularly through winter, once a year before the burning season is the standard. If you burned less than a cord of wood, you may be able to go every other year, but an inspection is still annual. Gas fireplaces need sweeping less frequently, but should still be inspected once a year to check the venting, burner, and any signs of blockage. See the full breakdown in our guide on how often to clean a chimney for wood-burning vs gas fireplaces in Dallas.
Cost varies widely depending on what's actually wrong. A chimney cap replacement is a quick, lower-cost fix. A full liner replacement is significantly more. Crown repairs fall somewhere in the middle. We don't quote numbers without seeing the chimney first, because two chimneys with the same symptoms can have very different underlying problems. See our 2026 chimney sweeping cost guide for general Dallas-area ranges.
Scheduling depends on the season. Fall (October through December) is our busiest period, when homeowners are getting their fireplaces ready for winter. During that window, book a week or two out if possible. In spring and summer, we typically have more availability. If you have a visible crack, smoke backing into the room, or any odor from the fireplace, call us at (214) 441-6336 and we'll prioritize accordingly.
That smell usually means moisture is getting in, either from a damaged or missing chimney cap, a cracked crown, or deteriorated flashing around the base of the chimney. Humid air draws existing creosote deposits into the room. A musty smell in summer is often worse because the stack effect reverses and outside air flows down into the flue. We address this in detail in our guide on smoke chamber signs like soot stains and back-puffing.
Yes, and it's one of the more underrated issues in this area. High-wind events blow off chimney caps, drive rain into the flue at angles that standard caps don't deflect, and deposit debris that becomes a blockage by fall. After a significant storm, a quick visual check of your cap from the ground takes two minutes. A bent or missing cap needs replacing before the next rain. Read more in our article on why Dallas summer storms matter for your chimney cap.
Repointing is worth doing when the brick itself is still sound. We remove deteriorated mortar to a depth of about 3/4 inch and pack in new mortar matched to the original. This restores the water seal and structural integrity without disturbing the brick. When more than 25 to 30 percent of bricks are spalled or cracked through, a rebuild becomes more cost-effective. Our article on repointing old mortar and restoring strength to historic Dallas chimneys covers the decision in detail.
Fall appointments fill fast. A chimney that hasn't been inspected since last season is a chimney that may not be safe to light. Don't find that out mid-January.
