I have used Southside Windows previously and when I was moving to my new house, I did not get a quote from anyone else as I knew who they were and what they do. No pressure, no hours long sales pitch, top quality windows/doors and professional fitters who clean up after themselves. I had 8 windows and 2 doors installed and I could not be happier. From Russell the owner to the girls in the office and the fitters, everyone is helpful, polite, they are superfast at replying to queries and they just get the job done. No hesitation whatsoever in recommending this company.

Southside Windows replaced all the windows in our second-storey flat. The originals were old (1970's or earlier) and there was secondary glazing too, so this probably wasn't a very easy job. We were concerned it would be really disruptive for us and the neighbours. From the beginning there was clear and streamlined communication with everyone at this company. They were helpful and prompt to come and give a quote. They were very professional during the installation - worked hard and cleaned up behind them and the windows seem to be excellent. We are really pleased and would recommend them to anyone.

I have just had three windows fitted by Southside Windows and am so delighted with everything. The windows are beautiful and have been finished off with care and attention to detail. The fitters were bang on time, pleasant and unobtrusive (I was working from home). They were so careful in my home, taking care by placing dust sheets everywhere and also hoovering up everything spotlessly afterwards. Southside were recommended to me by my neighbours and I would certainly recommend them to anyone. They have been informative, professional and delivered above and beyond what I had hoped for. 10/10!

I was needing new windows and doors and received a recommendation from our friends for Southside Windows to carry out work. Russell the proprietor came out and sent me a quote there was no hard sell, the price was the price end of story. The quote was received timeously and we agreed to carry out the work. All times agreed to were kept to and the windows and doors were fitted within the time frame set out. We were delighted with the product and the two fitters were terrific, arriving on time and clearing up after themselves. Overall really happy with company and would have no hesitation recommending Southside Windows to anyone.

From start to finish this has been a simple and seamless process. It was professional, friendly and everything was fully explained. I do think they went the extra mile to ensure everything was done as we asked. The fitters were fantastic and within 4 days we had everything done (it was a big house). The house looks fantastic now.

This is our second time ordering from Southside Windows. We have just had 10 windows replaced & are really happy with them, the guys (David & Ian) are pleasant, work hard & take pride in what they do, they arrived on time both days, and cleared up all the rubbish after the work was completed. We are now thinking of changing our conservatory windows & will be placing another order with them. I've delt with Russell for years & he has a lovely & polite family. I'm happy I ordered from them & would recommend them 100%.

We have been let down by different companies over the last few months so researched thoroughly before choosing Southside Windows. Right from our first contact with them their communication was first class responding quickly to our questions. On visiting our house he turned up on time and we felt no pressure to buy. We also found it extremely beneficial visiting the showroom as it helped us with our choice of windows and doors. We felt that the final price was competitive compared to other companies that had given us quotes. The work was to take 3 days and on the installation date they again turned up on time, working hard and tidying at the end of each day keeping any disruption to a minimum. We are extremely happy with our new windows and doors and would highly recommend Southside Windows

Southside Widows replaced 9 windows for us. The guys did a brilliant job. They were on time and worked hard. The job was completed on schedule in 3 days. In the bathroom and the kitchen the windows are behind the sink and difficult to access. Access from outside is also difficult. The guys worked well to find a solution and didn't leave a single scratch. They tidied up well. The house was left as if nothing had happened. We were very pleased with the work.

New double glazed windows

Required 7 new double glazed windows fitted in top floor flat. The owner of Southside Windows carried out the initial consultation and survey himself and quoted a price well within my budget. I was informed windows would be available with 4 weeks and take two days to fit. (From initial correspondence to final day of fitting eas exactly 28 days). The initial date given for fitting was inconvenient for me and Southside Windows had no problem st all in agreeing to a date the suited. Regarding the installation, the two fitters arrived promptly at 8:30 on both mornings and immediately got to work. Dust sheets, walking boards, etc were used to ensure little to no mess. As I was retaining the wooden surrounds already in place the fitting of these new windows didn't take as long as normal, finished by 2:30pm on day 1 and by 11am on day 2. I am delighted with the quality of both windows and workmanship and I would highly recommend Southside Windows.

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 !

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.
