Three Upstairs Window Units Replaced
I had six windows and a porch with composite door fitted by Demian. I have been in building most of my life and know a good tradesman when I see one, and Demian is up there with the best. His finish is superb and his always on time. I would highly recommend him to do work for anyone.

Conservatory Glass Pane Replacement
Excellent service. Gave an initial quote, came to measure up, confirmed price, ordered glass, and two weeks later came and fitted it. No fuss. Would more than happily recommend them.

FAQ's
Answers to our most frequently asked questions
What makes DW Windows different from other double glazing companies?
We’re a small local business with over 25 years of experience serving homeowners across South Wales. Our focus is on quality products, honest pricing, and friendly service — from your first quote to final installation.
What types of windows and doors do you install?
We supply and fit a wide range of uPVC and aluminium windows and doors, including casement, tilt & turn, sliding sash, and flush designs. Our doors include composite, bifold, French, and patio styles — all designed for style, security, and performance.
How energy-efficient are your products?
All our windows and doors are built with modern insulation technology and energy-rated glass. This helps keep heat inside during the winter and reduces unwanted heat in the summer — cutting your energy bills and making your home more comfortable year-round.
How long does installation usually take?
Most window or door installations are completed within a day or two, depending on the size and complexity of the project. We’ll always agree a clear timeline before starting work so you know exactly what to expect.
Do you offer a guarantee on your products and installations?
Yes — every installation comes with a comprehensive 10-year guarantee, giving you complete peace of mind that your investment is protected.
Will new windows really make my home more secure?
Yes. Our windows and doors feature multi-point locking systems, strong frames, and toughened glass — all designed to keep your home safe and secure without compromising on style.
Do you replace conservatories or build new ones from scratch?
We can do both. Whether you want to upgrade an existing conservatory with modern glazing or create a brand-new space, our team will design and install a solution that fits your home perfectly.
