Extensions- 8 Dec 2017
We couldn’t be happier with the professionalism and quality of workmanship from REA Construction. The project was delivered within budget and on time. We lived in the property during the work and we, our neighbours and the site were always treated with the utmost consideration. There were almost no hitches and, when they did occur, they were dealt with immediately and thoroughly. Our project team, led by Kristjan and Besi, were universally hardworking, organised and produced work to an excellent standard. Communication is great, the people are wonderful. Renato was someone I felt I could trust from the moment I met him and he never let us down. He and everyone at REA genuinely care about what they do and that their customers have a happy experience. We certainly did and would have no hesitation recommending them to others.

Extensions- 24 Apr 2021
Kujtim, working with his glazers, created a bespoke porch with a glass roof just as we asked. We were impressed with the finish of the internal plastering and Kujtim was able to come to our rescue one evening when we became locked outside the newly installed porch door. Although the project took longer than was anticipated we are happy with the quality of the finished product.

Restoration & Refurbishment- 25 Feb 2020
Malcolm and his team did great work on my house. The job consisted of full house redecoration, building bespoke shelving and built in wardrobes, loft boarding and installing ladder, replacing fencing and general pruning in the garden. They were able to turn their hands to all manner of jobs. Malcolm had a full team onsite every day and they finished the work ahead of schedule. At all times Malcolm was very responsive and worked hard to ensure that any changes along the way were accommodated. I would happily recommend Spring Construction and would not hesitate to use them again in the future.

Slawek and Andrew did an amazing job on the front and side of our terraced house. The quote was fair (and they stuck to it) and the attention to detail was refreshing. We were kept informed throughout the works - communication was excellent. I whole-heartedly recommend SM Refurbishment.

Bathroom Fitting- 22 Apr 2023
Younger brother Anti was a professional and I would hire again but beware of the elder sibling as his workmanship his poor, here is a list:- 1) the cupboard fitted under the stairs was misaligned and the hinges are loose. Paint job was poorly finished too. 2) cupboard fitted across the boiler was all bent. Anti came and fixed it. 3) varnish across door and skirting boards were done once and therefore have an uneven spread 4) the floorboards did not have enough glue placed in certain areas so it creaks 5) grout in some time are missing 6) really poor sealant work on the bathroom 7) broke my £2000 TV and then hid the evidence. I only found out after placing the furniture back in its place. In contrast Anti did a good job in fitting the radiator. If you can Illicit promises of Anti only completing the job without the older the brother then go for it or else give them a wide berth.

Norbi is an exceptionally talented carpenter. He was the team lead on our major building project when we restored our Victorian house over an 18 month period. All his work was superior, from replacing ceilings and ceiling roses, to laying the new herringbone floor with electric underfloor heating. He was always polite, well mannered, and respectful. Norbi takes pride in his work and genuinely cares about the finished result in your home, a rare quality amongst many. We cannot recommend him highly enough.

What qualifications and experience do you have as an extension builder in Waltham Forest?

An extension builder in Waltham Forest should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

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

What experience do you have with similar extensions in Waltham Forest?

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 Waltham Forest extension builder’s ability to deliver a result that meets your expectations.
