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.
New Window Installation

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.

We are delighted with our new sash windows. The workmanship and finishing both inside and out is excellent. The two workers who carried out the installation were very professional and cleared all of the debris as they progressed the works, leaving a very tidy interior and exterior. We would highly recommend 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.
