A family owned business who take pride & care in everything they do

Being a conscientious company we were fortunate enough to be able to offer our skills and services to a local family in the Hertfordshire area and had the privilege of working alongside the DIY SOS team.

Grey door

All surveys and quotes are carried out by ourselves and not by salesmen. At the initial appointment you will meet either Paul or Simon who will discuss your requirements and offer their wealth of knowledge and experience, answering any questions you may have and explaining processes.

At Windowman & Sons we have our own in-house qualified bricklayers and builders, so we're in a great position to offer a total refurbishment service in addition to supplying and fitting windows and doors.

We are a transparent company and welcome all customers to come and visit our showroom which is located in the heart of Hertford. Here you can take a look at a selection of our quality doors, windows and accessories for inspiration.

We even supply widows and doors which are suitable for listed properties and have been approved by 18 Borough Councils.

Continually striving to help & preserve the environment

One way we achieve this is by sourcing the most up to date Eco-friendly and energy efficient materials and use either Liniar or Eurocell to supply our windows.


By ensuring our uPVC, wood and aluminium windows, conservatories and doors are energy rated we're helping you reduce your energy costs. Your home will be more energy efficient so you'll be turning down your heating or using it less often. Thus helping you save both money and the environment. We are happy to advise you on the best choice of windows and doors for your home.

Rock Plastics
