Four scenarios drive most screen replacement work in Northern Colorado homes. Torn or damaged mesh is the lead: hail damage during Front Range storm season (May through September), pet claws and teeth, and age-related tearing. Sun-degraded mesh is the second driver: Northern Colorado sun on south- and west-facing elevations breaks down standard fiberglass within roughly 5 to 10 years.
Pet damage is the third path and the most common trigger for the pet-resistant upgrade conversation. The fourth is a planned mesh upgrade, where the existing screens still function but the homeowner wants pet-resistant polyester, solar mesh, or fine no-see-um mesh for foothills bug pressure. Moffat re-screens the existing aluminum or wood frame when it's structurally sound, and fabricates a new frame from commodity stock when it isn't. We don't install retractable or phantom screens; if that's the system you're after, we'll point you toward a specialist. See our window glass replacement page for buyers thinking about a screen plus glass package.
Moffat installs five screen mesh types, each ordered to the diagnosed opening and goal.
Frame material is selected at the diagnostic. Aluminum is the standard for residential and low-rise commercial work (durable, lightweight, available in white, beige, bronze, and mill finishes); wood fits heritage and custom-trim homes where aluminum reads wrong against the architecture. Frame color is coordinated with window trim per spec, with designers often choosing bronze or dark frames on contemporary builds and mill finish on traditional homes.
Standard residential mesh runs an 18×16 grid; no-see-um runs 20×20 or denser; coarser grids are available where airflow matters more than insect-blocking. Spline (the rubber gasket that locks mesh into the frame channel) is sized to the frame profile and mesh thickness so tension distributes evenly. Corner connectors, pull tabs, spring-plunger latches, and lift handles follow the original frame system or your accessibility preference. Some window manufacturers specify proprietary attachment hardware on certain window lines; we verify compatibility at the on-site visit before ordering frame stock.
On the residential side, the most common scopes are torn window screens across bedrooms, living rooms, kitchens, and sunrooms; sliding patio and French door screens, where pet-resistant mesh is often the right call; foothills properties and homes near water that need fine no-see-um mesh; south- and west-facing elevations where solar mesh reduces heat and glare; new-build homeowners upgrading from builder-grade fiberglass; and hail-damaged screens after Front Range storm season (May through September).
On the commercial side, we replace and re-screen window openings in low-rise buildings up to four stories: office windows, hospitality and restaurant interiors, and mixed-use buildings with operable windows. We don't pitch high-rise or curtain wall above four stories.
A Moffat technician confirms the damage condition (torn mesh, bent frame, broken spline, missing corner connector, damaged pull tab), checks the frame's structural integrity, measures the opening, and confirms your mesh-upgrade goals.
Existing frames are re-screened in our shop with new mesh, spline, corner connectors, and pull tabs as needed. New frames are fabricated from commodity aluminum or wood stock cut to the diagnosed dimensions. Typical lead time runs 3 to 7 business days from approved measurement. A century of Northern Colorado work means we know how to fit a screen so it tensions evenly and sits flush in the track.
Moffat technicians install, never subcontracted. We re-attach each screen, verify operational hardware (latches, pull tabs, spring plungers), and check the perimeter so daylight gaps don't admit insects.
We verify mesh tension, perimeter fit, and operational hardware at every replaced screen, register the warranty, and if anything needs adjusting in the first year, the same Moffat team that built it comes back to make it right.
Since 1921, Moffat has cut, fabricated, and installed custom glass and screens for Northern Colorado, and a century of work in Larimer and Weld County means we've seen every kind of torn mesh, bent frame, and Front Range exposure pattern these properties carry. The technician who diagnoses your screen is from the same in-house team that re-screens or fabricates the frame and installs the finished unit; Moffat technicians, never subcontracted. Three locations: Evans HQ, Loveland, Fort Collins.
The membership stack backs the posture: BBB Northern Colorado A+ accredited, NGA member, plus the Shower Door Professionals Co-op and our Greeley and Evans Chamber memberships. We carry every mesh type a Northern Colorado home asks for, and we'll tell you which one your application actually needs instead of upselling the heaviest spec by default. Commercial scope is capped at four stories.
Each mesh is engineered for a different use case: fiberglass is the standard, aluminum lasts longer, pet-resistant takes claws, solar blocks heat, no-see-um stops gnats. Standard fiberglass degrades under Northern Colorado sun in 5 to 10 years. Aluminum holds up longer and resists denting. Pet-resistant polyester is roughly seven times stronger than fiberglass (resistant, not pet-proof). Solar mesh blocks 70 to 90 percent of solar heat gain. No-see-um mesh (20×20 strands per inch or finer) stops gnats and small biting insects. Schedule a diagnostic visit.
Yes, in most cases the existing frame can be re-screened as long as the aluminum or wood frame is structurally sound. We replace the mesh and the spline, and swap corner connectors or pull tabs as needed. If the frame is bent, corroded, or rotted, fabricating a new frame from commodity stock is the right call instead. Schedule a diagnostic visit.

Pet-resistant screens are resistant, not pet-proof. Heavy-duty polyester mesh is roughly seven times stronger than standard fiberglass and holds up far better against claws, teeth, and repeated impact, especially on ground-floor windows and patio doors. A determined dog can still damage any screen, so we position pet-resistant as a major upgrade rather than a guarantee. Get a quote.
Screen replacement is diagnostic-priced because cost varies by mesh type, frame size, re-screen versus new-frame fabrication, accessibility, and quantity. A standard fiberglass re-screen on a bedroom window is a different scope from solar mesh fabricated into new aluminum frames across a sun-exposed elevation. Request a quote for a precise estimate.
Yes, solar mesh typically blocks 70 to 90 percent of solar heat gain on the windows it covers. The dense weave intercepts solar radiation at the screen before it reaches the glass, reducing cooling load during Front Range summer months. Most effective on south- and west-facing elevations. Schedule a diagnostic to spec solar mesh for sun-exposed elevations.
Restore the ventilation, view, and insect protection of your Northern Colorado home or building with screens diagnosed and built at an on-site visit. Since 1921, Moffat has worked custom glass and screens across Larimer and Weld County, and our diagnostic-first process means we confirm what your opening actually needs before any mesh is cut or any frame is fabricated. Standard fiberglass, aluminum, pet-resistant, solar, and fine no-see-um are all on the table. Residential and low-rise commercial up to four stories.

I do not hesitate to recommend Moffat Glass
"We needed our patio screen door replaced. Moffat answered the phone (something that 3 other businesses did not do), scheduled someone to come measure the same day, manufactured our non-standard sized door and installed it within a week. We have yet to hear from the other businesses we contacted who told us they would 'get right back' to us. The quality of customer service was very good. Everyone was friendly, professional, and expressed appreciation for our business. I do not hesitate to recommend Moffat Glass. They have been in Greeley for a long time and I can see why they have lasted."
I will absolutely be using Moffat again and I highly recommend them!
