Why a Conservatory

Year-Round Comfort

With a Guardian Warm Roof, your conservatory is as warm as the rest of your home in winter and stays cooler in summer. No cold spots, no condensation, no wasted room.

Adds Real Value

A quality conservatory adds up to 7% to your property value and significant usable square footage — without the cost of a full extension.

No Planning Needed

Most conservatories are permitted development. We'll advise on your specific property during the free survey — no planning headaches for most customers.

Bespoke Design

Victorian, Edwardian, lean-to, or P-shaped — every build is designed around your home, your space, and your budget. No off-the-shelf packages.

Guardian Warm Roof

Cold conservatory? Transform it into a room you’ll actually use.

The Guardian Warm Roof replaces your existing polycarbonate or glass roof with a fully insulated, tiled solid roof — transforming your conservatory into a proper habitable room without touching the walls or foundations. It’s one of the most cost-effective home improvements available, and we fit it across Tyne & Wear and County Durham.

  • Can be tiled or slated to match your existing roof
  • Dramatically better acoustic performance — no rain noise
  • Qualifies as a habitable room for planning purposes
  • Retro-fitted to your existing conservatory frame — no new foundations
  • Guardian Warm Roof system — tried and tested across the North East
  • 10-year product guarantee as standard

Highly recommended products and first class fitters

I am delighted with the windows and door fitted by John and son. Their windows have a unique safety feature which gives extra reassurance and the quality of the door and windows is excellent. Their work is carried out to an exceptionally high standard with absolutely no mess throughout.

Excellent service

Our patio doors were fit quick and easy, they installed doors using high security brackets and we feel so much more secure and safe within our home. Thank you to JJ Hunter Bros for making the installation easy and straight forward.

Garage door removed and French doors with side panels and windows installed

John was amazing start to finish! With explaining the process, the added safety features his windows offer which are the J clip system, a feature that adds the extra security your home needs. John arrived promptly for both the initial inspection and the survey. The morning of the job both John Sr and John Jr arrived promptly ready to go — very quick and thorough and left no mess after completion. We're very happy!!

New porch with unique window security

J & J Hunter Brothers fitted our new back porch, and we are delighted with the results. The quality of the work and attention to detail is exceptional. The windows installed also feature high security glazing brackets for extra security. John and John were a pleasure to deal with and we wouldn't hesitate to recommend them.

Sitting room / patio door fitting

John & son came recommended. Contact with John very straightforward, easy to deal with and all clearly explained. Job done in an agreed time slot. Very clean and tidy, attention to detail — specifically providing suitable protection to property and flooring. Would use again and definitely recommend!

They turn up on time and don't stop until the job is completed

I had a new upstairs window installed today, having used this company on several previous occasions. As usual I am delighted with the quality of the product and the superb workmanship. They are very respectful of your home, covering every surface and flooring with dust sheets. Afterwards they tidy up and vacuum everywhere. I would also like to mention how safe and secure I feel with the fitting of their High Security Window Bracket — a welcome added bonus!

Top Banana!

Good quality doors and windows, measured and fitted to a very high standard by John senior and junior. All doors and windows feature an additional unique (patent pending) security feature that makes it almost impossible to remove the glass from outside. Overall excellent.

New double glazing windows

Once again using JJ Hunter Brothers — another excellent job completed quickly, efficiently and personably. Both Johns carried out the work to a high standard. JJ also installed their new secure bracket ensuring the windows and my home in general is more secure. They look fantastic with the anthracite finish, massively improving the heat retention of my property. I highly recommend JJ.

Great workmanship

We had the whole house done — all windows replaced, front and back doors, and 3 sets of patio doors. They were very efficient, clean and tidy. John explained the new safety feature that his windows have which makes them much more secure and really difficult for intruders to gain access. This makes me feel much safer. Would highly recommend this company — my house looks amazing.

Highly recommended

John explained to me the best windows, including the partnership with Secure Windows Solutions, bringing together a new secure feature that no other company has — this security bracket prevents the window's glass panes from being removed and ensures a further level of security for my home. The team arrived and quickly got to work. Both Johns are polite, friendly and personable with a professional manner. I highly recommend J and J Hunter Brothers.

Amazing window company

John and John are superb and our family has used them on several occasions — most lately when they fitted new uPVC windows to my mam's bungalow. The quality of the fitting and the way they protect a house and clean up afterwards is second to none.

Excellent friendly service

Excellent from first contact getting our quote to completion of job. We had 4 windows and 2 doors replaced. Really friendly father and son — Big John and Little John — who work well together. Don't rush the job and finish to perfection. Punctual — said 7.45 and they were here at 7.45am. Worked hard for 2 days. Cleaned up after themselves. All in all delighted with the job and would definitely recommend.
