Our work

Look closely at the detail.

A window is judged from the pavement, so it is the horns, the bars and the meeting rails that decide whether it reads correctly. Sash windows, French doors and entrance doors we have made and fitted, with the specification for each.

How we work

Timber is the whole of the business.

We specify, supply and fit timber windows and doors across one region, and nothing else. That is why the schedule is right, the date holds, and the house is left as we found it.

Crispin Sash windows are built to our own specification. Our sections, our glazing, our ironmongery, our finish. Our name on the compliance certificate and our guarantee behind it. If something is not right in year eight, you ring us.

A new window should look as though it has always been there.

  • A date, in writing, before you commit. Standard specifications usually leave in four to six weeks. Larger orders, non-standard glazing and the spring peak can run to sixteen. We tell you which applies at quotation, and we do not quote dates we cannot hold.
  • A fixed price, held for 45 days. One figure, taken from a measured survey and itemised opening by opening. It does not move, it does not need chasing, and there is no discount that expires if you think about it.
  • Our own fitting teams. Directly contracted to us rather than found job by job, working to a written snagging schedule, and used to working around people who still live in the house. You are told who is coming before they arrive.
  • Half on order, half on completion. The balance is not due until the windows are in and you have signed them off, so nothing falls due for work that has not been done.

The process

Four stages, and a date at the end of each.

A survey, a schedule, a price and a programme, each with a date against it. The whole of it can be done by correspondence if you would rather not have anyone in the house until the fitters arrive.

STAGE 01

Measured survey

Ninety minutes on site. Every opening measured, glazing pattern, balance type, ironmongery and colour agreed, and access assessed.

STAGE 02

Schedule & price

A schedule of every opening with its sizes, pattern and finish, and a single fixed price against it, held for 45 days. We will also confirm whether the property requires consent before anything is ordered.

STAGE 03

Manufacture

Into production on confirmation, then glazed and finished before it leaves the works. Delivered on the date agreed at order, in stages where a programme requires it.

STAGE 04

Fitting & sign-off

Our own fitters, to a written snagging schedule. The balance falls due on sign-off and not before. The Building Regulations compliance certificate is lodged with the authority and sent on to you.
