Rooflight glass replacement in Berkhamsted

Glass replacement is a two-visit job. On the first, the fitter checks the frame, the gaskets and the drainage, and measures the existing unit exactly, including its thickness and glass type. That visit is charged and priced before booking. Once the new sealed unit has been made, the second visit takes the old glass out, cleans and checks the rebate, and beds the new unit in. We do this for rooflight glass units in Berkhamsted.

Where our fitters travel

Berkhamsted and the districts around it, HP4, HP1 and HP3, all sit inside our working area. So does the ground between Berkhamsted and Chesham (4 miles), and on towards Hemel Hempstead (5 miles). When a fitting team is booked, their travel is already in the quoted price, so it does not turn up as a surprise line on the final bill.

Included in the work

  • Frame rebate cleaned and checked for damage, corrosion or failed seals
  • Sealed unit ordered to match or improve on the original glass
  • Measuring visit to size the glass and identify its make-up
  • Matching the glass make-up — We identify the existing glass so the replacement performs at least as well.
  • Condition of the frame — We look at the frame closely before committing to new glass.

How the glass is replaced

The second visit is the quick one. With the new unit made to size, the fitters take the old glass out, check the frame and drainage paths, and set the new glass on packers so it sits square and drains properly. Seals and cappings are renewed where needed, the area is cleared, and you are shown what was done.

Planning, building control and Berkhamsted

In England, a new rooflight opening generally needs building regulations approval because the roof structure is altered and the glazing must meet energy rules: 2.2 W/m²K for a rooflight in an existing home, or 1.4 W/m²K (or WER Band B) for a roof window. Planning is often not needed on a house: permitted development covers rooflights that stand no more than 0.15 m proud of the roof slope and sit below the highest part of the roof. Flats, listed buildings and areas with an Article 4 direction are different, so we check your address first.

What to send us

Photos of the problem glass from inside and out, a rough width and length, and whether the rooflight opens or is fixed are enough to price the first visit. Add the postcode and how the roof is reached, and tell us if more than one unit has misted.

Common questions in Berkhamsted

How long does new rooflight glass take?

The new sealed unit is made to the measured size, so there is a gap between the measuring visit and the fitting visit while it is produced. We give you the expected timing when we price the glass, and book the fitting once it has arrived.

Is the measuring visit charged?

Yes. The first visit measures the existing glass and checks the frame, and it is charged. We confirm that price before you book. The fitting of the new glass is then priced in writing, so you see the full cost before anything is ordered.

Can I upgrade the glass while it is being replaced?

Usually. Solar-control, self-cleaning, toughened or laminated glass can be specified as long as the frame can take the thickness and weight. We check that on the measuring visit and price the options side by side.
