Weatherseal Windows And Doors works with homeowners across Wishaw, supplying and fitting double glazing windows, doors, and composite front doors. We are a local business, not a call centre operation, so when you get in touch you speak to people who actually do the work. If your windows are draughty, rattling, or just looking tired, we can help you sort it out properly.
What windows and doors do you offer?
We supply a full range of double glazing for homes in Wishaw, including uPVC casement windows, sash windows, tilt and turn windows, and bay windows. Every unit is built to measure, so your new windows fit the openings in your home correctly first time. We also carry composite doors, French doors, bi-fold doors, and uPVC back doors.
Our double glazing windows come with A-rated or A+ rated energy performance as standard, which means less heat escaping through the glass and lower heating bills over time. The frames are reinforced and the glazing units are argon-filled for better thermal performance than older single or basic double glazed units.
What security features do your windows and doors include?
Security is something most homeowners ask about, and rightly so. Here is what comes fitted as standard across our range:
- Multi-point locking systems on all uPVC windows and doors
- Toughened or laminated safety glass options available
- Shootbolt locking mechanisms on casement and tilt and turn windows
- Anti-snap, anti-pick, anti-drill cylinders on composite and uPVC doors
- Internal beading on all window units, so the glass cannot be removed from outside
- Reinforced composite door slabs with a solid timber core for strength
These are not optional extras. They come included because we think that is how window replacement should be done. You should not have to pay more to get a door that actually keeps intruders out.
How long does fitting take?
For most Wishaw homes, a full set of windows can be fitted in one or two days. A single window or door replacement is usually done inside a few hours. We will give you a clear timeframe before we start, and we tidy up fully before we leave.
Lead times from order to fitting vary depending on the products chosen, but in most cases you are looking at a few weeks from confirmation to installation. We will keep you updated throughout so you are not left wondering where things are up to.
What guarantee do I get on new double glazing?
All our double glazing windows and doors come with a 10-year manufacturer's guarantee covering the frames, glass units, and hardware. That covers things like seal failure in the glazing units, which causes the misty or condensation between the panes that many older windows develop.
Our fitting work is also guaranteed separately. If anything is not right after installation, we come back and fix it. There are no call-out charges for guarantee work on jobs we have completed. That is just how we operate.
Why choose local window installers rather than a national company?
Big national window companies tend to use high-pressure sales tactics and lengthy contracts. As a local business serving Wishaw and the surrounding area, we do not work that way. You get a straightforward quote, honest advice on what your home actually needs, and a fitting team that takes pride in the finished result.
Plenty of homeowners find that going local means better communication, quicker responses if something needs attention, and a team that genuinely cares about its reputation in the community. Our work speaks for itself through word of mouth and repeat customers.
If you want to talk through new windows, doors, or any other double glazing for your Wishaw home, give us a call on 0800 773 4907. We are happy to arrange a free, no-obligation quote at a time that suits you.
