Happy Customers
Jane Halls
A no-nonsense approach, I didn’t get all the spill talk about discounts and offers at the moment. It’s just a really good quote given at the time. No waste of time phone calls was given the lead time of 12 weeks, which suited us perfectly. Easy to pay the instalments on my phone. The day of installation was very efficient, which was done by Sid.
Moya Paul
Absolutely delighted. The paperwork and organisation were flawless, delivery was on time, the workmanship excellent and the product was of the very highest standard. I thoroughly recommend you to anyone looking for new doors or windows.
Alan
Superb after-sales service. Had porch and front doors installed a few years ago, after contacting Otter Windows, John Capon a man all knowing in this field, promptly arrived and corrected both problems in a true professional manner. I can not rate this company high enough and have recommended them many times.
Matthew Bulliman
Very positive.
Debbie was really helpful in keeping us informed throughout the process. On the day, the fitter was very professional and carried out the work to a very high standard.
Phil Cordon
I was particularly happy with the rear or back door, which I asked to be a barn door. The engineer was honest and gave me proper advice, so I ended up with a split/tilt/open barn door, which far exceeded my expectations.
All work was carried out to a professional finish, and the installer was a very pleasant chap who cleaned up behind himself and left the place clean and tidy.
