We ordered 18 windows, two patio doors and a front and back, doors. We had other quotes and selected Southside because they were recommended for their quality of build and products. We wanted really good quality and through advice from Russell selected doors , colours and asked a lot of questions. We were unsure of various aspects and Russell kept us straight on every thing. Others had quoted five days to fit maybe longer ! Russell came in and said he would take no more than four days ! The two fitters called and started a day earlier than originally planned and worked solidly through from 08.30 in the morning until after 4.00. They did an incredible job and it was completed in four days. We are delighted and the difference to our house is incredible. The fitters are very professional and 'nothing was a problem' A great service and product from Southside windows and we highly recommend them !

I recently had a palladio door fitted, from start to finish I had excellent service Russell came out to my property and the next day I received my quotation. I then visited the showroom and was greeted with some lovely girls in the office who were extremely helpful. The boys that installed my door were very good and well mannered. The installation was quick and the boys cleaned up after themselves . I highly recommend Southside Windows

We have used Southside Window Systems for over 20 years and would not even consider going elsewhere. We recently got Russell to provide a quote for new windows, door and French doors. The survey was quick and efficient, the whole process was very smooth and professional throughout. We were kept updated by the office staff of when the products would be delivered and we arranged the fitting date convenient to myself. The finished result was immaculately done, the quality of the windows and doors is impressive, and the whole area was cleared by their tradesmen. The after service was a nice touch to ensure we were happy with the whole process. I would definitely recommend Southside Windows all the way!

I just cannot rate this company high enough, this is my fourth house that Southside Windows have renewed my windows and doors in. Russell doesn't put any pressure on you to buy, helps to get you exactly what style you want and what suits your house both inside and with the interior finish. His fitters take good care of your home and have great pride in their workmanship. Russell's family members deal with the administration side and they are equally as friendly and approachable as he is. They have now installed at least three of my neighbours homes too. With one who has moved up north, even requesting if he would install windows in her new home up there. Outstanding family business, I cannot recommended them highly enough.

Windows didn't fit resulting in a 6 week delay and damaged my carpet and wall

They measured the windows up themselves. When they arrived to fit them they took my bedroom window out only to discover they'd measured wrong (by about 20cm!?!). I ended up with a window that didn't fit for 6 weeks in winter while they reordered. They damaged one of my walls and one of the carpets is badly stianed where they didn't put down sheets. They've offered a nominal discount of £100 but this is unlikely to cover both repairs. The quality of the fitting is pretty variable and the finish around a couple of windows is pretty poor. The guys doing the fitting were really friendly and helpful though.

The trader replied (on 15/12/2023)
Unfortunately, 2 of the windows should have been 2315mm, 1 wrote down 2135mm – a genuine mistake which cost my business over £1200. We ordered 2 new windows the same day. Our joiner should have ensured the new window was the correct size before removing the old window, but having made this mistake, he installed the smaller window and filled the gap, to ensure there was no gaping hole while the new windows were manufactured. As soon as they came in, we contacted you to arrange fitting and even offered you a Saturday installation which did not suit you, we fitted them when suited you. The joiners did put down a dust sheet, however it was a new brand and did not prevent the dust going through – these are all now in the bin. I am confident that the quality of the final fitting was to our usual very high standard, and I can arrange for the Window Advice Centre to independently check this if you wish. We offered you the £100 discount to get the carpet cleaned professionally, filled the small dent in your wall, and you paid the final balance of £3000, with no mention that you were unhappy with anything or the quality of the work. I am willing to arrange for a joiner to come back & rectify anything you are unhappy with, so please call if you would like to arrange this. We have been in business for over 27 years and do not like to have unhappy customers. The usual excellent standard of our work is demonstrated by the many 100’s of reviews we have.

Southside Windows (SW) installed 10 new windows in our house replacing tired old aluminium framed windows with new units. SW offered a wide range of styles and we were able to select the style that suited our requirements. The installation team arrived exactly when scheduled and carried out the work within the 2 days originally estimated. The team were obviously very experienced and carried out the work very professionally. In addition they were polite and very respectful of our home - they laid down dust sheets throughout the house before starting and tidied up at the end of each day’s work. The work was all carried out to the original estimate. The one minor issue I had with 1 window was sorted without question. The installed windows have greatly improved the look of our house. We are delighted with them and the service offered by Southside Windows.

Having decided to replace the old wooden windows and panoramic doors in our house I contacted a few companies. One of the companies was Southside Windows, which was recommended by neighbours who had been very pleased with their choice. After a meeting with Russell I decided to also go ahead with Southside Windows and have not been disappointed with any aspect of that decision. From the minute the men arrived their work was carried out with a pleasant attitude, respect for the property and neatness. With that said I was delighted with the finished work. I must also say that the whole experience was enhanced by my pleasant and helpful contacts with the office staff and Russell who called in to fix a minor problem the next day (10 minutes ). My regards and thanks to all.

The 2 men that came out to do the work were really professional, worked efficiently and cleared up any mess. They done and amazing job and only took a short break for their lunch. Didn't waste any time getting the job done, 7 windows and a door fitted in 2 days. Russell is great he comes and does a rough measure for quote purposes, if you're happy with that he'll come back to get exact measurments and fill in necessary paperwork. The total time for 2 visits from Russell come to roughly 30 minutes, no hard sell, a fantastic company to deal with, the office staff are great too, fantastic communication from them also, really quick in answering any questions you might have. Would definitely recommend them.

Double glazed sash windows.
Southside Windows installed double glazed sash windows in my house and I am delighted with the result. From Russell's first visit when we discussed the types of windows to the final installation it was a very straightforward and professional experience. A competitive quote and an excellent install team who were careful, quick and very helpful. I am very impressed by the work, the windows are very high quality and a perfect replacement for the orginal wooden sash windows so the period look of my house is retained. Highly recommend if you are looking to replace your windows.

7 windows and patio doors supplied and fitted hassle free from start to finish. Russell came to quote the job then returned for a final measure before windows were ordered. Fitters arrived exactly on time on our chosen date. They covered all surfaces with dust sheets before starting installation and their workmanship was first class. Overall Highly Recommended. Absolutely delighted with end result.

This is the third time I have used this company over a twenty year period and the service and after service is still second to none. From the first visit from Russell with a quick, no nonsense quote, plus dealing with Nicole and the other admin staff to the completion of the windows, it was five star service! I had seven windows installed by Ian and David, lovely guys who worked non stop for two days and cleared up as they went along. Thank you, I’m delighted with my new windows and would highly recommend Southside Windows.

No hard sell salesman tactics, Russell was very professional and friendly and carried out an initial 5 minute measure of the windows and a quote breakdown was emailed to me afterwards - and provided the lowest quote out of 3 other companies I had approached. Other companies salesmen loitered for 40+ minutes chopping and changing their quotes. Fitters were very quick and polite, finishing 6 very large windows and replaced sills over 1.5 days. Great communication from everyone at southside windows, very positive experience for what could have been a stressful experience with such a big job being carried out.

Guys from Southside windows were brilliant from start to finish. Even the planning of the job and booking in dates with the ladies in the office went smoothly. The work men arrived bang on time, covered all flooring and work area to keep everything tidy. Constantly tidying up as they went. They finished the job earlier than expected but still to a very high standard. Just like to say thanks for there efforts. Would one hundred percent recommend to anyone wanting new windows fitted.

Installed 10 new windows and 2 doors at our house. Russell very knowledgable, quick to quote and no hard sell. Not the cheapest but still competitive for the best windows and doors (Rehau and Palladio). Fitters arrived as scheduled and completed in just over 2 days all in. Polite hard working guys who left a high quality installation. Good communication with the office too. Can’t recommend highly enough.

I contracted with Southside Windows on a recommendation from a trusted source and have not been disappointed. Very quick in getting a quote together and agreement on date to start work. The guys that came were well briefed, easy to be around and delivered an outstanding quality of work. The job was a big one to replace all windows and both doors on a two-storey house. This included two large bay windows. All the work was completed to our satisfaction without any discussion or debate. Very high quality levels and, relatively, very little mess. You may be able to find cheaper but be careful what you pay for. These guys have quality at the heart of what they do and it all comes from having a team of highly skilled tradesmen. Well done and thank you.

Russel from Southside windows measured up and gave us not the cheapest but competitive quote for the work. He was quick to point out possible issues and advantages of each type of window and their specifications. He got straight to the point, gave us a firm quote and the work started and finished on an agreed timescale. The fitters were respectful, and trustworthy (we left them alone on the property) and worked hard right through each day fitting one side of the property to reduce any inconvenience. The windows performance is as he said - reducing the road noise but not eliminating it totally. Russel (Southside windows ) tells you how it is, with no false promises. one minor issue was the sill heights were slightly higher, however, Southside windows paid to have new vertical blinds rather than realigning the already finished job. Overall good product, job done well and any issues resolved - no fuss what more could you reasonably expect.
