Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterTrusted Chimney Cap & Crown for Fairfax Homeowners
A failed chimney crown or missing cap in Fairfax is rarely loud. Water gets in, freeze-thaw cycles do their work over a few winters, and by the time a homeowner notices staining on the ceiling or spalling brick on the exterior, the repair bill has tripled. We’ve been inspecting and repairing chimney caps and crowns in Fairfax since 2009, and the pattern is consistent: the homes that get a camera scan and a written report every year are the ones that catch crown hairline cracks before they become liner replacements.
Our chimney cap and crown service in Fairfax covers cap installation, cap replacement, crown repair, crown coating, multi-flue caps, and custom caps. Every job starts with a camera-scan inspection that produces a documented photo record before we recommend anything. That record is yours to keep, and it’s the basis for every written price we give you. Call (571) 443-8256 for a free estimate from our Fairfax team.
What Our Chimney Cap & Crown Service Includes
Cap Installation
A chimney cap is the metal hood that sits over the flue opening. It keeps rain, snow, leaves, and animals out of the flue, and it has a mesh screen that also stops sparks from leaving the chimney and landing on your roof or in your gutters in Fairfax. When we install a cap at Level Two Chimney Fairfax, we measure the flue opening precisely, select a cap sized to the flue tile inside diameter, and secure it so it will not lift in the wind that comes through Merrifield and Mantua every March. A properly installed cap should last 10 to 15 years in this climate, provided it is stainless steel or copper rather than galvanized.
Cap Replacement
Caps fail in specific ways: the mesh rusts through, a limb knocks the cap off, or the mounting screws corrode and the cap shifts, allowing water down one side of the flue. In Fairfax, where we get both heavy summer thunderstorms and ice events, a shifted cap is a slow leak that degrades mortar joints inside the flue. We replace caps with stainless steel or copper units matched to the existing flue size, and we document the condition of the old cap with photos before we touch anything. If the old cap is salvageable and you do not need a replacement, we’ll tell you that plainly and show you the photos that support the call.
Crown Repair
The crown is the concrete or mortar slab that forms the top surface of the chimney, sloping away from the flue to shed water. Crowns in Fairfax crack for two main reasons: they were poured too thin originally, or they were cast without enough slope, so water ponds and freezes. A cracked crown lets water into the brick and mortar below, and over several winters that means spalling brick faces and deteriorating mortar joints. We repair crowns by removing loose material, preparing the surface, and recasting the crown with a proper slope and a drip edge that keeps water off the brick face. Crown repair is not a caulk-and-paint fix; it is structural work, and we write the scope and price before we start.
Crown Coating
When a crown is still structurally sound but showing hairline cracking or surface wear, a flexible crown coating is often the right call. The coating is a waterproof membrane that bridges fine cracks and restores the crown’s ability to shed water without a full recast. It is less expensive than crown replacement and buys years of service when the crown itself is not failing. We apply crown coatings as the manufacturer specifies, and we include photos of the crown before and after so you can see exactly what was coated and why.
Multi-Flue Cap
Homes in Fairfax with two or more flues, common on properties built with a fireplace on one level and a furnace or water heater flue adjacent, need a single cap that covers the whole crown and spans all flues. A multi-flue cap mounts over the full chimney top and screens every flue opening. This is the best solution when individual caps will not seat properly due to tight spacing or a deteriorated crown edge. We fabricate or order multi-flue caps to the exact crown dimensions, and we secure them with brackets that will not let the cap walk in wind.
Custom Cap
Not every chimney is a rectangle. Older Fairfax homes, especially the brick colonials and ramblers in Fairfax City and the neighborhoods off Braddock Road, often have odd flue sizes, offset layouts, or stone crowns with irregular perimeters. A custom cap is cut and fabricated to the exact measurements of your flue and crown, and it is typically made from stainless steel or copper in a gauge heavy enough to hold shape for years. We take field measurements, then fabricate the cap to spec. The written quote includes the material, the fabrication lead time, and the installation work, all documented so there is no ambiguity about what you are paying for.

Brands We Service for Chimney Cap & Crown
We work with Olympia Chimney and Famco caps and accessories more than any other brands in the Fairfax market. Olympia makes a deep line of stainless and copper caps, including multi-flue systems with interchangeable mounting brackets, and we keep the common Fairfax sizes in stock. Famco caps are common on older northern Virginia homes; their mesh and base designs are straightforward, and when a Famco cap fails it’s almost always the mesh or the mounting hardware, not the hood itself, which means replacement rather than full cap swap.
We also regularly install and service Copperfield caps when a homeowner wants copper, knowing that copper will patina to a dark brown in Fairfax without staining the masonry the way some galvanized caps do. DuraFlex products come into play when the cap work ties into a liner issue, since a new liner often means a new top plate and cap assembly at the flue. Whether you have one of these brands or a cap the previous owner bought at a big-box store, we can inspect it, quote replacement or repair in writing, and show you the photo evidence behind the recommendation. Most of what we see in Fairfax isn’t brand failure; it’s installation failure, undersized caps, or metal that was never appropriate for this climate.
BeforeAfterSigns You Need Chimney Cap & Crown Right Now
- Water staining on the ceiling or wall near the chimney chase. This means water is getting past the top of the chimney and traveling down through the structure. It rarely shows up in the room directly below the chimney; in Fairfax split-levels and center-hall colonials, it often appears a floor down or along a wall offset from the flue.
- Spalling brick faces or mortar chips in the firebox or on the exterior near the crown. Spalling is the brick surface flaking off, and it is caused by water that froze inside the brick. Once spalling starts, each freeze-thaw cycle accelerates it, and the crown is almost always the entry point.
- You hear animals or birds in the flue, or find nesting material near the damper. Squirrels, chimney swifts, and raccoons all use uncapped flues in Fairfax, and their nests are a fire hazard and a blockage. A cap with proper mesh stops this completely.
- The cap is visibly tilted, rusted through, or missing a section of mesh. A tilted cap lets water run down the flue wall on one side, and a rusted mesh means rain gets in while sparks can get out. Both are cheap to fix and expensive to ignore.
- You smell a damp, musty odor from the fireplace after rain. That smell is water that entered through the crown or cap and is sitting in the smoke chamber or soaking into the flue liner. It means the top of the chimney is not sealing the way it should, even if you cannot see damage from the ground.
Our Chimney Cap & Crown Process - Step by Step
- 1
Camera inspection and condition report. We run a camera down the flue and inspect the crown and cap from the roofline. You get a photo record of what we found, including any crown cracks, cap damage, or water entry points, before we quote anything.
- 2
Written scope and fixed price. Based on the inspection, we write a scope that names the exact work: what gets replaced, what material we’re using, what the warranty covers, and what the total price is. That price is fixed before we start. Clause 1 of the Haven Standard requires it; we’ve done it on every job since 2009.
- 3
Prep and protection. We protect the roofline, set up our equipment, and remove the old cap or prepare the crown surface. If the crown needs recasting, we build forms and set them for the correct slope and drip edge. If a cap is being replaced, we dry-fit it to confirm the measurement before securing it.
- 4
Installation and sealing. The new cap goes on, or the crown gets repaired and coated. We use mechanical fasteners, not construction adhesive, for caps. Crown repairs get cured properly before any coating goes over them, because coating over uncured mortar is how you get a repeat failure in twelve months.
- 5
Documented completion record. After the work is done, we photograph the finished cap or crown from the roof and run the camera again if the flue was involved. You get the full photo record with your invoice. That record is Clause 4 of the Haven Standard, and it’s been standard practice here since 2009.
How Much Does Chimney Cap & Crown Cost in Fairfax?
What moves the price most is roof access, chimney height, and whether masonry repair is needed around the crown before a cap goes on. A chimney on a steep-pitched roof in a neighborhood like Kings Park West costs more to access than a low-slope rancher in Fairfax City. The way to avoid overpaying is to see the photos. If a company tells you the crown needs $2,000 of work but won’t show you a camera image or a close-up photo of the crack, get a second opinion. We’ll give you one free on any written estimate, ours or a competitor’s. Just call (571) 443-8256 and we’ll schedule it.

Frequently Asked Questions - Chimney Cap & Crown in Fairfax
What is a chimney cap and crown?
A chimney cap is the metal cover over the flue opening that keeps water, animals, and debris out, and the crown is the masonry slab at the top of the chimney that caps the brick and sheds water away from the flue. Both of them fail over time in Fairfax’s freeze-thaw cycles, and when they fail, water gets into the chimney structure and the house. The cap and crown together are the first line of defense against the most expensive chimney problems we see.
How long does chimney cap and crown work take?
A straightforward cap installation or replacement takes about one to two hours on site, including roof access and setup. Crown repair or recoating usually takes half a day to a full day, depending on whether we’re recasting or coating. Custom cap work adds fabrication lead time of one to three weeks, but the installation itself is a single visit. We tell you the timeline in the written scope before scheduling.
How much does a chimney cap and crown cost in Fairfax?
Single-flue cap installation in Fairfax is $225 to $450, cap replacement $200 to $600, crown coating $350 to $700, full crown recast $800 to $1,800, and custom or multi-flue caps $1,500 to $3,500 depending on size and material. The quote we give you is fixed in writing before work starts, and it includes the cap or coating material, labor, and the completion photo record. Call (571) 443-8256 for an exact price on your chimney.
Do you service Olympia Chimney and Famco caps?
Yes, we install and service Olympia Chimney, Famco, Copperfield, and DuraFlex caps and chimney accessories throughout Fairfax. We keep common Olympia and Famco Fairfax sizes in our local inventory, which means most cap replacements don’t have to wait on a shipment. If you have a different brand, we can still inspect and replace it; the key variable is the flue size and existing mounting hardware, not the logo on the hood.
Is a missing or damaged chimney cap an emergency?
Not usually an immediate emergency, but it is a problem that gets more expensive the longer it waits. A missing cap means rain is entering the flue with every storm, and in Fairfax’s freeze-thaw winters, that water is working on your flue liner and smoke chamber. If you have a chimney fire or active water intrusion into the living space, call us right away and we’ll prioritize it. For cap and crown issues that haven’t caused interior damage yet, booking within a week or two is reasonable.
What kind of warranty comes with cap and crown work?
Every cap and crown job we do in Fairfax includes a written warranty naming the materials, the workmanship coverage period, and what’s excluded, and it’s backed by the 365-Day Done Right Promise: if it’s not done right, we make it right. The warranty is in your written scope before we start, not buried in an invoice after the fact. The photo record from the completion report is part of what makes that warranty enforceable on both sides.
How should I prepare for a chimney cap or crown appointment in Fairfax?
Clear the area around the fireplace inside and keep pets contained while our techs are on the roof and working around the chimney chase. There’s nothing else you need to do; we bring roof protection, tools, and materials, and we handle access from the exterior. We’ll text you when the assigned tech is on the way, and you’ll get the documented record when the job is done.
