I can't praise Southside Windows high enough. After contacting this company we had a visit from the owner who was very helpful and gave us good advice on the windows we chose. We received a quote next day which we were very happy with and agreed for the fitting to go ahead. The fitters David and Craig made an excellent job of the work. No mess, very clean workers. Delighted with our new windows. Would highly recommend Southside Windows.

Replacement Porch

Southside Windows had the best quote which was the initial reason for use. The existing Porch was rotten but had a new roof which we were advised could be re-used. Porch was installed within 2 weeks of quote and deposit paid. Unique design of the old Porch gave the Team some issues but was all sorted and the finished job looks good. We chose brown outside and white inside UPVC as cost measure but prefer the look now installed. Job was completed within one full day and all old materials and waste was removed. Very happy with the work.

Amazing Transformation, Love Them!

Delighted with our new sash windows, they have completely transformed the outside our house. Attention to detail was amazing. Very hard working, friendly and tidy. Everything was on schedule, great price and knowledgeable - from initial quote, showroom visit, onsite work and after care. Inside the finish was carried out to a very high standard with excellent joinery work. There is hardly any outside noise now and zero drafts which is wonderful, didn’t realise how bad the old windows were until the new ones were fitted! Can't fault anything with the Southside Windows Team and have already highly recommended them to friends and family.

New double glazing to flat
From first come contacting southside windows they have been nothing but professional . Owner Russel came and measured up and let me know all the options available . No hard sell or anything like I have had in the past with other companies . Agreed to go ahead . Two boys came on day of fitting and in two days had all the windows and verandah doors fitted . All done to a faultless installation . All windows and doors are perfect with rose finish outside to fit in with the building and white inside . I’d highly recommend Southside windows to anyone considering replacement windows or doors .

Fantastic service. Extremely happy with product, fitting, and efficiency. It’s made such a huge difference for noise reduction and heat efficiency in the flat. They sent two teams as I had 10 large windows and they did the job to a high standard and efficiently. Well worth the investment.

This was a tricky job due to very large windows and a challenging parking situation. The guys did a fabulous job with no complaints and a very cheery, 'can do' attitude. They worked very hard all day and completed the job as promised the same day and to a very high standard, including a decent clean up. Highly recommended.

The whole team at Southside Windows are amazing. Russell came out to give me initial quote and then again when I added to the order. I have some unique shaped windows so nothing was straightforward. Nicolle in the office kept me updated frequently and was very helpful with her suggestions. Then came the 4 days of fitting which I was dreading but the fitters Mick and Ian were outstanding, they went out of their way to make it as easy as possible for me. Their work is first class.
