If you're based in Renfrew or the surrounding area and you're thinking about new windows or doors, the first step is simple. Give us a call on 0141 310 9821 and have a quick chat about what you're looking for. There's no pressure, no sales pitch, just a straightforward conversation about your home and what you need.
From that first call, we'll get a good feel for the work involved and arrange a time to come out and see you. Most people have questions at this stage, and that's completely fine. We're happy to talk things through before anything is booked in.
Your Free Home Survey
Once we visit your property, we carry out a full survey at no charge. We measure every opening accurately, check the existing frames, and take note of anything that could affect the installation. Getting the measurements right first time means no delays further down the line.
This is also when we sit down and go through your options properly. We'll explain what products suit your home, talk about energy ratings, and give you honest advice rather than steering you towards the most expensive choice. You'll come away knowing exactly what you're getting and what it's going to cost.
Choosing the Right Products for Your Home
The range we supply covers uPVC windows, composite doors, French doors, patio doors, front doors, and triple glazing as well as standard double glazing. uPVC is a popular choice because it's low maintenance and holds up well in the Scottish climate. Composite doors offer a more solid, timber-like appearance with a reinforced core for added security.
Colours and finishes matter too. Your windows and doors don't have to be white. We offer a good selection of colours and woodgrain foil finishes, so you can match your existing style or give your home a fresh look. All the products we fit carry an 'A' energy rating as standard, which makes a genuine difference to how warm your home stays and how much you spend on heating.
Security is built in rather than bolted on. Multi-point locking systems come as standard across our door range, and our window units include internally beaded glazing so the glass can't be removed from outside.
Manufacturing and Lead Times
Once you're happy with everything and your order is confirmed, your products go into production. We aim to have everything manufactured, delivered, and fitted within ten weeks of your order being placed. That's a realistic timescale, not an optimistic one.
We'll keep you updated as the job approaches so you're not left guessing. When your installation date is confirmed, you'll know exactly when to expect us and how long the work should take. No vague windows of availability or last-minute changes.
What to Expect on Fitting Day
Our fitting teams are experienced and tidy. They'll protect your floors and furniture before any work starts and take care removing your old frames. Depending on how many units are being replaced, most jobs can be completed in a single day. Larger projects may run to two days, but we'll be upfront about that before we start.
Each window and door is fitted, sealed, and checked before we move on to the next one. You won't be left with gaps or draughts overnight. By the time we pack up and leave, everything will be fully operational and your home will be secure.
Any old frames and waste material are taken away with us. You shouldn't have to deal with any mess once the job is done.
Aftercare and Your 10 Year Guarantee
Every product we supply and fit comes with a full ten year guarantee. That covers both the materials and the installation workmanship. If anything develops a fault within that period, contact us and we'll sort it out. You won't be passed between manufacturers or left chasing anyone.
We're a local business and our reputation matters to us. Customers in Renfrew and the surrounding towns know where to find us, and we intend to keep it that way. Aftercare isn't an afterthought here. It's part of how we work.
