Reliable and reassuring

I recently employed A&B Construction to remove a brick supporting wall and install an RSJ in our home. We are not from London and were always worried about employing a builder we did not know, but Agim and his team were amazing. They were prompt, efficient, polite and tidy and made us feel very confident in what seemed to us like a stressful time. I highly recommend A&B Construction and feel I now have a reliable builder I can call on at any time.

High standards throughout

As a builder myself, I have been used to providing and asking my workers for a high standard. I subcontracted A&B London Construction and went to look at what they were doing many times. I needn't worry — polite, on time, clean and job well done.

Quality delivered on time

I hired them to do a loft conversion and extension. They did it with a reasonable price and completed the job within the time frame with amazing quality.

Well managed from start to finish

It gives me great pleasure to write a few words of personal recommendation in support of Agim Lleshi who supervised and undertook a building project for me. In brief, Agim assessed, planned and oversaw an extensive building and decorating project in my 1960s semi-detached house. This included creating a new studio and fitting two new kitchens and shower rooms, as well as redecorating the rest of the house both internally and externally. His team included a carpenter, plumber an electrician and decorators and all the work that was carried out was undertaken on time. The site was left clean and tidy at the end of each day and progress was discussed with me on daily basis. In summary I would have absolutely no hesitation in recommending Agim and his team, who carried out all works to a very high standard.

Professional work and communication

Agim and his team are excellent professionals. Not only did he complete the installation of the beam, he went on to quote for the drainage, blockwork and roof. Everything was completed to a high standard and good customer communication. Will be using A & B London again for other projects.

Knowledgeable, courteous and dependable

A pleasure to deal with. Agim and his team worked hard to a very good standard. They often worked later than expected so they were ready to move onto the next stage the following day. Agim was very knowledgeable of all building regulations and offered solutions when needed. All his team were courteous, polite and knowledgeable. This was the first time I have used A&B but I would have no hesitation in using them again and recommending them to others.
