Painting & Decorating- 13 Sep 2026
Fantastic service from Swiftfix. They painted and decorated my entire flat and did an excellent job from start to finish. Everything was completed to a very high standard, and they were professional, reliable and easy to deal with throughout. The price was also very reasonable for the amount and quality of work involved. I’m extremely happy with the finished result and would definitely recommend them to anyone looking for a professional painter and decorator.

Extensions- 17 Jan 2018
A Total disappointment Ricky agreed to install a porch and roofing. He advised us to install new pvc doors agreeing to fit the roof after. This started mid November with a promise to be completed before Christmas. On his instruction we paid other workers to complete the preparation works and then the morning of the Job he sent a text message advising that he will no longer be able to attend the job. Thankfully we were able to find a local reputable roofer -plasterer-tiler who completed the work to a very high standard I feel very let down as I had put total trust in his promise to complete the work. Unfortunately based on this I cannot confidently recommend Ricky to a friend family, or anyone else.

Kitchen Fitting- 31 Jul 2019
Can't recommend this guy enough! Pat is a professional from start to finish. He came to quote me for a complete kitchen refit, within a few days he had emailed me a detailed quote and we agreed a date. My kitchen came with many unforeseen problems and challenges but Pat rose to them all. Aside from being a skilled carpenter and a skilled builder he is a great problem solver. He is reliable,trustworthy and very approachable. When I was getting stressed out he would calm me down and reassure me that everything would be ok. Sounds silly but my kitchen issues would have stressed a saint out! To summarise, my kitchen has turned out beautiful! Pat has done the work to a very high spec and gave it the wow factor! I absolutely love my new kitchen and am so happy that I chose Pat to come and do it for me. Look no further!!! Hope he posts my before and after pics on here and you can see for yourselves!

Kitchen Fitting- 14 Jan 2026
My initial experience with Solis Power Limited was Leo’s immediate response within 30 minutes, visited my property to view my kitchen. He gave a full detailed breakdown of price list that explains each work to be carried out. Suggested materials to use also help with the purchase. Leo and his team are perfect working together, cleaned after themselves each day. They installed new electrical unit, also introduced registered gas man to run gas pipes and also connect the gas hob. Plumbing work was excellent too. Leo also helped with the measurements of splashback and splash splatter guard. The work was carried out within five working days delay was due to shortage of splashback in the store. I highly recommend Leo and his team.

Extensions- 7 Apr 2025
Quotes were provided and the job was agreed upon. The project involved a full house restructuring and extension build. However, after several stages of work, communication with Jas was lost, and his co-worker took the lead on site. Several issues arose, such as recommending smart plumbing equipment for purchase, but their plumbers were unable to install it. The tiling, skirtings, and tiles were not completed. Tiles around the columns were cracked. After Jas's team abandoned the project, another plumber had to install all the remaining items. The job was left unfinished, and we had to find alternative contractors to complete it. Significant time and money were wasted due to persistent communication problems, failure to issue invoices, and numerous other issues. Eventually, Jas and his main labourer stopped responding and disappeared, ignoring phone calls and WhatsApp messages. Be aware of these potential issues.

Couldn’t recommend this guy enough! He was incredibly helpful, professional and went above and beyond to help us when we were in a bit of a difficult situation. He genuinely saved us from what could have been a massive issue and we’re so grateful for his help. Really friendly, knowledgeable and clearly takes pride in his work. It’s rare to come across someone who cares that much about helping their customers. Would 100% recommend and will definitely be using him again in the future. Thanks again!

Will my home extension meet all building regulations and planning requirements?

Your New Cross extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in New Cross?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the New Cross extension builder’s ability to deliver a result that meets your expectations.

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most New Cross extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
