Loft conversion roof windows in Cheltenham

Already bought a loft roof window, or still deciding which one to get? Both are fine. For loft conversion roof windows in Cheltenham we either source a suitable unit and install it, or fit the one waiting in your garage. Fit-only jobs are usually priced from your photos and measurements, while supply-and-fit and replacement jobs get a free survey first. Whichever route you take, the opening, the upstand or flashing, and the delivery are checked before anything is fixed down. Properties in GL50 and the surrounding districts are covered on the same terms.

Areas around Cheltenham we cover

Looking at a property near Cheltenham but not quite in it? We work across GL50, GL51 and GL52 and outwards to Tewkesbury, Gloucester and Stroud. Give us the full postcode when you get in touch, because access, parking and the route for a large unit all depend on the exact street. Those details shape the quote for any job around Cheltenham.

Buying your own, or letting us supply

Supply and fit tends to suit people who would rather not pick a unit from a catalogue. We look at the roof, the opening and how you use the room, then put a loft roof window on the quote that fits all three. Fit-only suits people who already know what they want, or have one on site. We are happy with either. The difference is who stands behind what: on fit-only, the maker or retailer covers the product, and our workmanship guarantee covers the installation.

On the day, we cover

  • Matching or combination flashing kits for windows side by side
  • Insulation collars fitted so the room's insulation meets each frame
  • Underlay dressed and taped around every frame
  • Combination flashings — We order combination flashings where windows sit close together.
  • Approved loft drawings — We work to the window positions on your approved loft drawings or agree changes with your builder first.

What happens on the day

Where a job takes one to two days, the split is usually structural work first and finishing second. Early on, the fitters cut or prepare the opening, trim where needed and prepare the upstand or flashing. Then a loft roof window is lifted in, fixed and made weathertight so the roof is sound before anyone moves inside. Plasterboard, trim and filler for the reveal come after. Each evening the work area is swept, and at the end the glass is cleaned and the team talks you through what was done.

Regulations for Cheltenham properties

Replacing a rooflight in an English home is a controlled fitting: it has to be self-certified by a scheme-registered installer or notified to building control. We are not registered with a competent person scheme, so replacements we fit are notified with a building notice, and the new unit has to meet current energy limits. Adding a new one usually means a building regulations application, because joists or rafters are trimmed. On the planning side, most house rooflights are permitted development if they project 0.15 m or less; on a side slope the glass must be obscured and fixed unless the opening part is over 1.7 m above the floor.

Details that speed up your quote

What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around GL50 and we will come back with a quote or a survey date.

Common questions in Cheltenham

Do I need planning permission for a rooflight in Cheltenham?

Often not. Many rooflights fall under permitted development, provided they do not project beyond the national limit and meet the other conditions that apply in England. Conservation areas, listed buildings and some flats are different and may need consent. Because the rules depend on the property, we confirm what is likely to apply at your address and point you to the planning authority where an application is needed.

Will my new loft roof window leak?

A correctly fitted unit should not. Leaks usually trace back to the detail around the frame: an upstand that is too low, a membrane or flashing that is not dressed properly, sealant applied to a damp surface, or water ponding against the kerb. We fit to the maker's instructions and check each of those points. The fitting carries a written workmanship guarantee, with its terms set out on your quote.

Can you remove and dispose of the old rooflight?

Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.
