Drafty frames, condensation between the panes, windows that stick or won’t lock properly — these aren’t just annoyances, they’re signs that your windows are no longer doing their job. Replacing them is one of the most effective upgrades you can make to your home: it cuts energy bills, reduces noise, improves security, and instantly lifts the appearance of your property. At Nova Windows & Doors, we handle the full replacement process — measuring, sourcing, and installing — so you get the right result without the hassle.
How Do You Know It’s Time to Replace Your Windows?
Most homeowners wait until something breaks before replacing their windows — but by that point, old windows have often been costing them money for years. If you feel cold drafts near closed windows, notice your heating or cooling running harder than it should, see visible damage to frames or sills, or find that your windows are difficult to open, close, or lock securely, it’s time for a proper assessment. We’ll visit the property, take a look at what you have, and give you an honest view of your options.
We carry a full range of replacement window styles — casement, sliding, tilt & turn, bay, and fixed — in uPVC, aluminium, and timber-effect frames. We’ll help you choose the right combination for each room based on ventilation needs, energy performance, aesthetics, and your budget. All windows we supply meet current energy efficiency standards.

Once you’ve chosen your windows, our installation team takes over. We remove the old units carefully, prepare the openings, fit the new frames, insulate, seal, and finish — inside and out. Every window is tested for smooth operation and a proper weatherproof seal before we consider the job complete. We also clear all old materials and leave the site clean.
What’s Included in Our Replacement Service
Our window replacement service is handled entirely by our own team — no subcontractors. Here’s what’s covered from start to finish:
- On-site measuring and existing window assessment
- Product selection guidance (style, material, glazing specification)
- Careful removal of old window units and frames
- Professional fitting of new windows to each opening
- Expanding foam insulation and weatherproof sealing
- Internal and external trim and finishing
- Full operation test and final quality check
- Removal of all old materials and site cleanup
Most single-room or whole-home replacement projects can be completed in a single day. We’ll confirm the expected duration when we visit your property and provide your quote.
As a family-owned business, we treat your home with the same respect we’d give our own. We show up on time, keep disruption to a minimum, and make sure you’re happy with the result before we leave. If anything needs attention after installation, you’ll always reach a real person on our team — not a call centre.
