Glasgow homeowners have been choosing us for double glazing, doors, and home improvements across the city and the surrounding areas. What sets our products apart starts with the glass itself. Every unit we fit is argon gas filled, which dramatically improves thermal performance compared to standard air filled units. You get noticeably warmer rooms and lower heating bills without having to do anything differently.
Our windows carry an A+ energy rating, and the frames are made from reinforced uPVC that holds its colour and shape for years without needing painting or varnishing. On the security side, every window and door we supply comes with multi point locking systems as standard. The hinges are reinforced too, so the whole unit works together to keep your home secure, not just the lock barrel.
Windows And Doors We Supply And Fit
We cover a full range of products, so you can get everything sorted through one company rather than dealing with multiple contractors. Here is what we fit:
- uPVC double glazed windows
- Triple glazed windows
- Composite front doors
- uPVC doors
- French doors
- Patio doors
- Bi fold doors
- Residential and back doors
- Conservatories
Composite doors are particularly popular right now. They combine a solid timber core with a glass reinforced plastic outer skin, giving you the look of a traditional door with far better insulation and strength. They resist warping and fading far better than older timber or basic uPVC doors, and they come in a wide range of colours and panel styles to suit your property.
How The Installation Works
Once you have agreed your quote, we aim to have your products manufactured and fitted within ten weeks. That timescale covers the full process from order through to the final clean up on the day. Our fitters arrive on time, work cleanly, and take away all the old frames and packaging when the job is done. Most single window or door installations are completed within a day, while larger jobs like a full house of windows will typically take two to three days depending on the size of the property.
Every installation is managed properly from first contact through to completion. You will not be passed around between departments or left wondering what is happening. One point of contact, clear communication, and a finish you are happy with before we leave.
Your Guarantee And Our Insurance
Every product we supply and fit comes with a full ten year guarantee. That covers both the materials and the installation workmanship, so if anything develops a fault you are covered without any grey areas. We are fully insured for all the work we carry out, which protects your home and gives you a proper paper trail if you ever need it for a house sale or mortgage survey. We do not cut corners on this, because it matters to the people we work for.
Why Glasgow Homeowners Call Us First
