Fantastic service. Don't hesitate to use. Peter and his team were superb, right from the start and throughout the work. Really professional, friendly explaining choices, options, and the quality of windows and workmanship just superb. We had our upstairs sash windows replaced (Leystonstone area) and a downstairs door draught proofed and re-glazed. Really please we went with Peter's team. John who did the main installation was great to deal with, clearly very experienced, and guided us through any decisions needed as things went along. Clean, courteous, high standards of work, really pleased. Many thanks

Highly recommended. Reliable, professional service. Cannot fault Peter and his team. Am delighted with the results.
We’ve had four of our windows replaced by Peter and his team and can’t recommend them highly enough! The initial consultation was really informative and Peter is great - responsiveness and general communication was fantastic from the outset and he is so enthusiastic about his trade. Our painting request was slightly unusual and Peter helped us work out exactly what we wanted. The fitting took 4 days and we were really pleased with the level of care, attention, and general consideration Peter and his team took whilst in our property - we were super impressed by how tidily they work and cleaned up after themselves. The windows are lovely, very well made and very nicely finished. Peter and the team struck us as genuinely lovely guys - nothing was too much trouble and all seem really passionate about windows and making sure we were happy with the product and fitting. Thank you again and we’re very much looking forward to having you back in the not too distant future to do the next lot
We were very pleased with the quality and appearance of the completed work.

What to check before you hire
Worth checking yourself
Always confirm credentials and quotes with the business directly before hiring.
Be wary of high-pressure 'today-only' discounts and a salesperson who won't leave. A reputable window or door firm gives you a written, itemised quote you can take away and compare against others.
Never pay the full price up front; a modest deposit with the balance on completion is normal. Ask what deposit protection or insurance-backed guarantee you get if the firm stops trading before fitting.
Get the specification in writing (frame material, the glazing units and their energy rating, and any trickle vents) so you can check you got what you paid for.
