Modern Orangery Extension


Orangeries offer Dorset homeowners the best of both worlds, intelligently combining the light and glass that conservatories provide with the insulating walls and ceiling of an extension. Seamlessly bridging the gap between a conservatory and an extension, their partially solid, multi layered structure provide homeowners with a multitude of benefits.

Checkatrade Review - April 2023

Double Glazing Fitted into 1889 Traditional Stone House

"Due to various factors we had to delay the installation of the windows by a month. Premier Windows were very flexible over this delay and when the time came to fit the windows turned up on the day and did an excellent job of fitting the windows into a relatively complex masonry window reveal. I had acoustic glass fitted, works well. I was very pleased with the internal and external reveal trimmings and, externally, the masonry effect sealant. On the other house elevation I also took the opportunity to have some double glazing panes replaced, general maintenance plus lock replacements."

Checkatrade Review - January 2023

Premier Windows are outstanding – A wonderful team.

"This work is the 4th Premier Windows has carried out for us, the first being more than ten years ago (Bi-Fold doors, leaking conservatory and blown windows). Every time-absolutely delighted. An old advertising jingle comes to mind “Nice People To Do Business With”. The whole process has been a pleasure; we knew exactly what was happening and when - perfect! Nathan takes the trouble to understand and clearly explains our options. Enabling us to be confident in our choice. As always, I shopped around, but simply no other company I contacted regarding this replacement door came close."

Checkatrade Review - July 2023

Replacement of French doors

"Having used this company before we wouldn't choose anyone else. The fitters arrived on time and were extremely careful in removing the wooden doors so that no damage was caused to the plaster. The highly professional tradesmen then expertly fitted the new upvc equivalent- a vast improvement on the old doors."

Checkatrade Review - March 2023

Replacement windows and front door

"I found Nathan and his company excellent from the initial quotation through to the completion of the work. They were prompt and completed the work within the suggested time frame. The work was completed to a good standard and the fitters were friendly and easy to deal with. I am very happy with the instaand quality of the windows and door. I can definitely recommend Premier Windows."

"First class fitters, LEE and IAN, very curtious, clean and tidy,could not find fault with their knowledge and workmanship, absolute credit to Premier Windows, would have absolutely no hesitation to use these fitters again, and would highly recommend Premier Windows."

Checkatrade Review - May 2023

New Front Door

"The door and frame size was measured and we went through all the options. A few weeks later, after it had been made to the exact measurements, two fitters came out, removed the old frame and door and fitted the new. Only took two hours for the whole operation including caulking beautifully. Highly recommended."
