Customer reviews

We have worked with Tomasz and his team several times, most recently in relation to a variety of challenging work at our listed house in Gloucestershire. If you want someone that you can rely on 100%, who can undertake work of all types with the same level of care, skill and professionalism, it is very difficult to imagine a better choice than TW Construction London. They completed also a full refurbishment of our house in London, covering everything from structural work to finer decorative work, and the quality of their work was fantastic. Tomasz and his team are highly skilled, completely reliable and extremely hard-working – we could not recommend them highly enough. - Gavin

I am very pleased to say that from inside the roof appears 100% water-tight and during the recent intense rain we felt very glad indeed that you and your team had done the good work last autumn. If/when we have any further building work to be done, we shall certainly contact your firm to discuss it. - David

I have used T.W. Construction London for over 6 years for both large and small projects, notably a high specification total refurbishment of a house including a complicated basement excavation and roof installation. The work is always completed to a very high standard with excellent levels of communication between all parties and close attention to budget and time constraints. In particular, T.W. Construction London operate very professionally and are readily available for any minor follow up requirements or post project works. I would recommend them most highly. - D. Burt
