We were looking for a local firm to refurbish our family home and came across Fortis Builders. We are so delighted we found them. From the very first informal chat with Martin it was clear that their approach was open and accessible. This continued throughout the project with straightforward, clear and realistic assessments of the work required and it’s cost. They turned the daunting prospect of a desperately needed full refurb into a feasible project. Martin and George brought together a highly skilled and professional team whose attention to detail across the board was exemplary, from the hidden steelwork and drainage to the installation of the kitchen and bathrooms to the final paintwork finish. Fortis Builders are prepared to go the extra mile. They did not flinch at our tentative request to save and repair our badly damaged parquet flooring, seeking out and matching reclaimed blocks, painstakingly cleaning them and blending them into what was left of the original floor. The final result is beautiful. We are very happy to commend their work and have no hesitation in recommending Fortis Builders. - Joanna

It was a pleasure to work with Fortis Builders for a high end residential project in Fortis Green. I found George and Martin to be very professional and reliable. Most importantly they took great pride in their work, which was of an impressive standard in craftsmanship and construction. The project was completed on time and on budget and they have been diligent in sorting out the few snagging items that inevitably arise on every building project. I will be delighted to use their services in the future and would not hesitate to recommend them. - Brian

Fortis Builders Ltd completed a challenging project for me which involved boiler work, under floor heating, kitchen and bathroom installations. The project was on a high value property in N6 and required the installation of expensive fixtures and fittings. George, Martin and the team were punctual, hard working and delivered a high standard of workmanship throughout, I wouldn't hesitate to recommend them to homeowners, architects and project managers. - Michael

Fortis Builders did an excellent job, whilst keeping to cost and time, and also being flexible to any amendments we requested. An Architect had been engaged early to see through all approvals required by the Council for Planning and Building Control, Structural Survey and Party Wall. The Architect prepared a Schedule of Works which Fortis Builders used as their baseline for quoting, and together with a Gantt Chart for timing, was an important document to direct and manage progress. Fortis Builders were always friendly and it was a pleasure to work with them. Fortis Builders worked well with the architect and regular billings were initiated by the architect on the basis of work done. Their skills were recognised and all parties showed respect for each other which made the whole endeavour quite a pleasure. The most time consuming part was to specify and source the fittings, especially as we were overseeing the whole project from abroad. We are delighted with the results. Our house has been transformed. - Marlie

From the beginning of the project they kept me fully involved with the design and layout of the kitchen and advised best locations for the appliances. They also took into account the height of cupboards etc to ensure I could reach things easily. From the tiles to the painting, any changes that I requested were done without issue and they were more than happy to oblige. Due to the age and location of the boiler and heating system, I required this to be replaced and the boiler moved. Best locations for the boiler were discussed and agreed and the system replaced with the latest model. All safety checks were carried out and warranty provided. I found them very easy to approach with any questions and appreciated the advise regarding the best materials for the various aspects of the works. The work areas were kept very tidy and all who were on site were extremely helpful and friendly. Over all, this was a very good experience for something that could have been stressful. I would highly recommend this company and will definitely use them again for future projects." - Sian
