Fitting across Market Harborough and nearby
Distance is rarely the deciding factor. A roof in Corby, 10 miles from Market Harborough, gets the same survey, the same written quote and the same fitting process as one in LE16, NN18 and NN16. What changes the price is the job itself: size of unit, roof type, access and lifting. Kettering, around 10 miles out, is treated the same way.
Included in the work
- Joints water tested and the glass cleaned inside and out
- Measuring visit to size the glass and identify its make-up
- Old glass taken out safely and removed from site
- Matching the glass make-up — We identify the existing glass so the replacement performs at least as well.
- Weight and lifting — We plan how a heavy pane gets onto the roof and into the frame.
How the glass is replaced
On the fitting visit, the room below is protected first. The beads or cappings come off, the old unit is lifted out with suction lifters, and the rebate is cleaned and checked for damage or blocked drainage. The new sealed unit goes in on fresh packers and gaskets, the cappings are refitted and sealed, and the glass is cleaned. Most glass swaps take half a day once the new glass is made.
Planning, building control and Market Harborough
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 Market Harborough
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.
Is new glass or a new rooflight better value?
If the frame, gaskets and drainage are sound, new glass is usually the cheaper fix. If the frame is cracked, distorted or leaking at the kerb, a full replacement is better value. After the measuring visit we price both so you can compare.
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.
For a repair in Market Harborough, start with photos and the postcode; we confirm the visit price before anything is booked.
