Testimonial
Hi
all, quick E Mail just
to say thanks - brilliant product, the Bower Beams saved me so much work
it is untrue!! Easy to fit and work perfectly, I know they are quite simple
as a concept, but so often you buy workarounds and they just prove to
be a waste of time. Absolutely would use you again and will recommend
to a builder friend as this was such a positive experience and easy job
for me to do on my own as a DIY fix. I did it over two lazy, coffee fueled
mornings (4 joists) but reckon I could have done it in one morning if
I'd been bothered.
Thanks to all and take care. Samna.
