Sealawns, Barry

My 5 widows were installed on my 2nd floor flat in1 day thanks to the efficient service of the staff and Welsh Windows both in placing the windows and the clean up. This was possible with the help of a "Spyder" instead of scaffold. I will not hesitate in recommending this company to anyone interested in replacing windows.

Replacement glazing for UPVC windows

Punctual, hard working and courteous. The team attended to a few unforeseen "extras" with patience and good humour.

We are very pleased with the result.

Excellent job

Cavan and his team fitted a composite front door to my 87 year old mothers house, they did an excellent job, very clean. The whole experience from ordering, measuring up, fitting and aftercare was highly professional. The integrity and professionalism of this company is second to none our family has used them for many years, I cannot recommend them highly enough, fantastic job thank you 😊

Excellent service

Excellent service.
Couldnt fault them.
Very friendly and professional.
Phoned up for a quote and had someone round within a few days and work done within a few weeks.
Very honest compared to another quote I had.
Told me only double glazing unit needed replacing not whole window.
Saved me a lot of money.
Great value for money.
Good quality windows.
Work took under an hour and the men that did the work were friendly and professional.
Even took their shoes off before they entered the house.
They cleaned up after themselves and even put my nets and curtains back up for me.
I couldn't fault the brilliant service.
I would highly recommend this company.
