Full-service exterior painting — surface cleaning, minor repairs, caulking, priming, and premium weather-resistant finishes. [Request Inspection](https://cmac-new-concept.vercel.app/quote) ## Exterior Painting, clearly scoped. CMAC specializes in delivering trustworthy, affordable, and high-quality exterior painting solutions. The scope is full-service: prep work, surface cleaning, minor repairs, and priming, finished with premium, weather-resistant paints. ## Prep is the job Paint does not fail because the paint was bad. It fails because it was applied to a surface it could not bond to. Chalk, dirt, mildew, loose edges of the previous coat, bare wood that was never primed — every one of those is a bond failure waiting to happen, and no product overcomes any of them. On a typical repaint the preparation takes most of the labor, and that ratio is the honest signal of whether a bid is real. A quote that is cheap because it skips prep is not cheaper; it is a two-year paint job priced as a ten-year one. ## Washing and chalk removal Chalking is what an aged coating does under ultraviolet exposure: the binder that holds the pigment breaks down at the surface and releases loose pigment powder. Run a hand down a sun-facing wall and if it comes away colored, the wall is chalking. Paint applied over chalk bonds to the powder, not to the substrate, and it releases in sheets within a couple of seasons. Removing it means washing with detergent and mechanical agitation, then rinsing thoroughly and letting the substrate dry. Mildew is a separate problem that has to be killed rather than rinsed, because live spores painted over will grow through the new coating. High-pressure washing is a tool used carefully — too much pressure drives water behind siding and into window assemblies and erodes soft wood, and a wall that is still wet inside will blister the new coat from underneath. ## Scraping, feathering, and repair Loose and peeling coating is scraped back to sound material. The edge that remains is then feathered — sanded so the transition from bare substrate to the intact old coating is a ramp rather than a step. Skipping that step telegraphs every scrape mark through the finish coat, which is why some repaints look worse from ten feet than they did before. Minor repairs happen at this stage because this is when the damage is visible. Rotted trim ends, split fascia, failed siding butt joints, nail pops, and damaged sill wood all get addressed before anything is primed. Painting over rot hides it for exactly one season. ## Caulking — and what not to caulk Caulk seals the joints that are meant to be sealed: siding to trim, trim to trim, around window and door casings, and at penetrations. A high-quality elastomeric or siliconized acrylic sealant is used because those joints move with temperature and the bead has to move with them. Cracked, hardened caulk is cut out rather than layered over, because a new bead over a failed one has nothing sound to grip. What matters just as much is leaving alone the joints that are supposed to drain. The bottom edge of a lap siding course, the weep holes at the bottom of a window frame, and the drainage gap at the base of the wall are all deliberate openings that let water that got behind the cladding escape. Sealing them turns a wall that drains into a wall that holds water. This is one of the most common ways a well-intentioned paint job causes damage. ## Priming Every area scraped to bare wood gets spot-primed. Bare wood is porous and absorbs binder unevenly, so finish paint applied directly to it starves in the substrate and leaves a flat, weak film exactly where the surface was already vulnerable. Primer also blocks tannin bleed from cedar and redwood, which otherwise stains through a light-colored topcoat as brown discoloration within months. Knots and resinous areas need a stain-blocking primer specifically. Bare metal — flashing, fascia wrap, railings — needs a primer formulated for metal, and bare masonry needs a masonry primer for alkalinity. ## Why south and west walls fail first Walk any older house and the paint condition varies dramatically by elevation. The south and west walls take the highest cumulative ultraviolet dose and the highest surface temperatures, because west walls catch direct sun during the hottest part of the afternoon. Ultraviolet radiation breaks down the binder, which produces chalking and fading. Heat drives daily expansion and contraction cycles in the substrate and in the film. The two together age a coating on a west wall roughly twice as fast as on a north wall of the same house. That has practical consequences. It is why fading looks uneven and why a spot repair on a west wall rarely color-matches the adjacent original. It is why the sunny elevations justify better products and more careful prep. And it is why the honest recommendation is sometimes to repaint the whole house rather than the two walls that look bad, because painting only those two guarantees a visible line at the corner. ## Acrylic latex or elastomeric One hundred percent acrylic latex is the standard exterior finish for wood, fiber cement, composite, and previously painted surfaces. It stays flexible as the substrate moves, it resists ultraviolet degradation and chalking far better than older formulations, it breathes enough to let residual substrate moisture escape rather than blistering, and it cleans up with water. On siding and trim it is nearly always the right product. Elastomeric coatings are a different animal, built for masonry: stucco, concrete block, poured concrete, and fiber cement in some applications. They go on far thicker than conventional paint and cure to a rubbery film that stretches, which lets them bridge hairline cracks in masonry that ordinary paint would simply crack along. That thickness is also the limitation. An elastomeric film is much less permeable, so applying it to a wall with a moisture source behind it — rising damp, a leak, a wall that cannot dry outward — traps that moisture and the coating blisters and delaminates in sheets. It also does not belong on wood siding, which needs to breathe and moves differently than masonry. Fix the water problem first; elastomeric is a crack-bridging coating, not a waterproofing membrane. > Exterior painting is the right time to look at everything the paint is covering. Trim rot, failed caulk at the windows, and a gutter that has been streaking one wall are all cheaper to correct while the crew is already on the ladders. ## What exterior painting includes ### Prep-first scope Cleaning, scraping, feathering, minor repairs, caulking, and priming before any finish goes on. ### Chalk and mildew handled Aged surfaces washed and treated so the new coating bonds to substrate, not to powder. ### Repairs before paint Rotted trim, split fascia, and failed joints corrected rather than painted over. ### Drainage left open Weeps and lap edges stay unsealed so the wall can still drain behind the cladding. ### Right coating for the substrate Acrylic latex on siding and trim, elastomeric where masonry actually calls for it. ### Premium weather-resistant paints Products chosen for the ultraviolet and heat load your sunny elevations actually see. ## How CMAC handles exterior painting 1. **Inspection and color** — We assess every elevation for chalking, peeling, and repair needs, and settle colors with you. 2. **Wash the surfaces** — Detergent washing and rinsing to remove dirt, chalk, and mildew, then time to dry. 3. **Scrape and repair** — Loose coating removed and feathered, and damaged wood and trim repaired or replaced. 4. **Caulk and prime** — Moving joints sealed, drainage paths left open, and bare wood and metal spot-primed. 5. **Apply the finish** — Premium weather-resistant coating applied at the specified film build, cut in at every edge. 6. **Walk it with you** — The job is reviewed elevation by elevation and touched up until you sign off. ## Exterior Painting questions ### What kind of company is CMAC? CMAC Roofing and Sheet Metal LLC is a veteran-owned and operated construction and remodeling company founded by Christian Viveiros. We handle roofing, gutters, garage doors, restoration, and exterior work for residential, commercial, and multi-family properties. We are a GAF Master Elite® certified contractor and a GAF President’s Club award winner. ### What states does CMAC serve? Five: Texas, Oklahoma, Arkansas, Tennessee, and Georgia. CMAC publishes office addresses and local contact information for Dallas–Fort Worth (Haslet), Houston (Rosenberg), Austin (Georgetown), Oklahoma City, and Nashville. Arkansas and Georgia inquiries route through the regional line; no walk-in office is published in either state. ### What are CMAC’s core principles? Earn the customer’s trust, use only quality materials, and deliver exceptional workmanship. The company operates under the motto “Integrity Truly Matters,” and the practical version of that is simple: document what we find honestly, quote what the job actually requires, and stand behind the work after the crew leaves. ### What does GAF Master Elite® mean? GAF awards Master Elite® status to a small fraction of roofing contractors in North America. It requires proof of proper licensing, adequate insurance, and a sustained record of quality installations and customer satisfaction. Practically, it means CMAC can offer enhanced GAF system warranties that non-certified contractors cannot, and that GAF has independently vetted the company. CMAC is also a GAF President’s Club award winner. ### How much does a new roof cost? There is no honest answer to that question without seeing the roof. Price is driven by measured square footage, the pitch and complexity of the roof, how many layers have to come off, how much decking has turned out to be rotten, the material system you choose, and whether the work is going through an insurance claim or being paid out of pocket. That is why CMAC inspects and measures before quoting rather than publishing a per-square number that would be wrong for most homes. The inspection and the written estimate are both free. ### Do you charge for an inspection or an estimate? No. The inspection, the damage documentation including drone photography, and the written estimate are all free and carry no obligation. If the roof does not need work, we will tell you that. ## Related services - [Exteriors](https://cmac-new-concept.vercel.app/services/exteriors) - [Siding](https://cmac-new-concept.vercel.app/services/exteriors/siding) - [Decks](https://cmac-new-concept.vercel.app/services/exteriors/decks) - [Replacement Windows](https://cmac-new-concept.vercel.app/services/exteriors/windows) ## Start with a free inspection.
