Survey to certificate, including what you need to do on fitting day.
Knowing the sequence makes the job far less disruptive, and it makes it obvious when an installer is skipping a step.
This is how a straightforward replacement job runs.
The technical survey confirms sizes, opener positions, sill details, lintels, access and glazing specification. This is the point at which the price becomes fixed, because everything unknown has now been checked.
Frames are made to the surveyed sizes. Bespoke colours, heritage detailing and specialist glass extend lead times, which is why we confirm dates after survey rather than before.
Old frames come out, new frames are fitted, levelled, fixed and sealed inside and out. Internal making good, sill finishing and waste removal follow. Ask any installer to confirm in writing that these are included.
Replacement windows are notifiable under building regulations. As a Certass-registered installer we self-certify the work and register it, so you receive the certificate for your records and for a future sale.
The survey is free and it's the point at which your price becomes fixed.
Most standard replacement jobs are completed in a small number of days, confirmed at survey once access and quantity are known.
Someone needs to provide access and sign off at completion, though you don't need to be present the whole time.
It evidences that the installation complies with building regulations, and conveyancing solicitors routinely ask for it.
