Where the heat actually goes out

Windows are worth doing, and they are rarely the biggest loss in the house. Both of those things are true.

Fitters installing a large window unit into a rear wall
  1. The glass is the small part

    On most houses the roof and the walls lose more than the windows do. That is why a surveyor starts with the loft rather than the glazing.

  2. The frame and the seal are the rest

    Old frames leak air around the edges as much as through the glass. Replacing them stops draughts you had stopped noticing.

  3. Which changes the ventilation

    A house that has just stopped leaking air still makes the same amount of moisture. Trickle vents are not an optional extra on a tightened house.

  4. So they get specified together

    Glazing spec, trickle vents and extract, considered as one thing. It is the difference between a warmer house and a warmer house with mould in the corners.

What we fit

Replacement windows
uPVC, aluminium and timber-effect, in the styles that suit the property rather than the ones with the best margin.
Doors
Composite front doors, French and patio doors, and bi-folds where the opening and the lintel allow it.
Trickle vents and background ventilation
Specified with the windows, because current building regulations and a tightened house both require it.
Making good
Reveals, sills, plaster and external sealing, so it does not look like something was replaced.

How the job runs

Day one

Measure and specify

Openings measured, styles agreed and the ventilation worked out at the same time.

Within days

The quotation

Itemised by opening, so you can do some now and some later if you would rather.

Lead time

Manufacture

Made to your measurements. Lead time depends on the frame and the finish, and you get a date.

One to three days

Installation

Out, in, sealed and made good. Most houses are done in a couple of days.

Within weeks

FENSA registered

Building control notified through FENSA, and the certificate posted to you.

What happens once we leave

Frames move, seals settle, and hinges want adjusting once.

Your paperwork

FENSA certificate confirming building control notification, plus the manufacturer documentation and glazing specification.

A two year guarantee

On our workmanship, in writing, transferable if you sell, and insurance-backed, alongside the manufacturer's warranty on the frames.

One adjustment, free

New doors and windows settle. If something needs easing in the first year, we come and ease it.

One number, not a call centre

The people who fitted them, not a national sales operation.

The questions we get asked most

Are windows the best way to save energy?

Rarely the best first move. On most houses the roof and the walls lose more, and cost less to fix. Windows are worth doing, usually after those.

Do I need trickle vents?

On a replacement window, current building regulations generally require background ventilation where it existed before, and a tightened house needs it regardless. We specify them rather than leave them off to save a few pounds.

Is it FENSA registered?

Yes, 47480. Building control is notified through FENSA and the certificate comes to you.

How long does new windows take?

Most houses are one to three days on site. The lead time before that depends on the frames.

Do you do bi-folds?

Yes, where the opening and the lintel allow. That gets checked at the measure rather than assumed.

Will you make good afterwards?

Reveals, sills, plaster and external sealing are part of the job.
