Our uPVC Windows, Doors & Roofline Services in Bolton

Dunders uPVC

Terraces in Great Lever and Halliwell often still have their original timber frames, which means draughts and cold spots we can put right with uPVC built for that kind of housing stock. Out towards Heaton and Markland Hill it’s a different job — bigger, often newer homes off Chorley New Road where the focus is more on a clean, energy-efficient finish. With over 20 years’ experience across Bolton, we fit windows suited to your property, no matter the type.

"Dunders uPVC replaced our old windows and doors, offering great advice for our requirements without being pushy. They are friendly, their workmanship is excellent, reasonably priced, and they made sure everything was clean and tidy afterwards. I would 100% recommend their services."
Sammy Foy
"Finally, a tradesman who turns up on time, doesn’t charge the earth, cleans up, and goes out of his way to make sure things are completely done properly. Highly recommended!"
Michael Lindsey
"We have Dunders uPVC several times, from the supply and fitting of double glazed windows to the replacement of a "blown" glazing unit. He is courteous and hard working, never leaves a mess as he cleans up after the job has been done. He charges a fair price for a good day's work. I am happy to recommend him."
Ian Battersby
Father and son team did an A1 job on our fascias, soffits, gutters, windows and door. Great work, not rushed. Helpful and accommodating. I'll never go anywhere else! Even gave us the courage to try a purple front door - it looks amazing! Thank you gents!

Our uPVC Windows, Doors & Roofline Services in Bolton

uPVC Windows Bolton

Older frames in terraces around Great Lever and Halliwell let in draughts and cold that a modern uPVC window puts a stop to — better insulation, less noise, and no more condensation on the inside of the glass. On newer homes, like those off Chorley New Road toward Heaton and Markland Hill, it’s more about upgrading to something more efficient without changing how the property looks. Either way, it’s a job we’ve done across Bolton for over 20 years.

uPVC Doors Bolton

Older terraces in areas like Tonge Moor and Breightmet tend to have narrow porches and frames that have stopped sealing properly over the years. We fit uPVC doors precisely to these openings, improving security and insulation without changing how the property looks. We’ve been fitting doors across Bolton for over 20 years, whatever the property type.

Composite Doors Bolton

Whether it’s a period entrance in Harwood or a newer property out towards Lostock, composite doors are a stronger, more secure step up from standard uPVC, in a wider range of colours and finishes to suit either. It’s the kind of job we’ve done across Bolton for over 20 years, on period and modern homes alike

 

Glass Replacement Bolton

Misted or cracked units show up a lot in Bolton’s older housing stock, especially around Deane and the town centre terraces. We replace failed double glazing quickly and cleanly, restoring warmth and clarity without the cost of a full new frame. Whatever the property, our 20+ years in Bolton means we get it sorted quickly and properly.

 

Warm Roof Conversions Bolton

Conservatories from the 1990s and early 2000s often struggle with the local climate. Our warm roof conversions replace the old roof with a fully insulated tiled system, making the room usable all year round.

Soffits & Fascias Bolton

Exposed brick and timber roofline takes a beating over time, particularly on the older stone-built properties around Egerton as well as the Victorian terraces further into town. Our uPVC soffits and fascias give long-lasting, low-maintenance protection whatever the property type — built on 20+ years of roofline work across Bolton.

Your uPVC Questions Answered

Most homes are done in a day, sometimes two for a full house or where older frames need extra work. We’ll give you a clear timeframe when we quote.

 

 

Very likely, yes. Original late-60s frames were never built to modern insulation standards, so swapping to uPVC is usually one of the most noticeable upgrades you can make to a Talbot or Greenside property.

 

In almost all cases, yes. We fit to the existing opening wherever possible, so there’s no need to disturb surrounding brickwork or plaster.

 

 

Yes — a good amount of our work is on exactly this kind of property, and we fit uPVC that’s built to cope with original, less-insulated timber frames.

 

 

Yes — whether it’s a terrace in Great Lever or Halliwell or an older stone-built property around Egerton, we fit in a way that respects the look of the property rather than making it stand out.

 

 

Yes — we regularly work across the wider Bolton area, including Westhoughton, Farnworth and Horwich, alongside Bolton town itself.
