Loft conversion roof windows in Stevenage

Already bought a loft roof window, or still deciding which one to get? Both are fine. For loft conversion roof windows in Stevenage 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 SG1 and the surrounding districts are covered on the same terms.

Covering SG1 and neighbouring districts

Stevenage and the districts around it, SG1, SG2 and SG4, all sit inside our working area. So does the ground between Stevenage and Hitchin (5 miles), and on towards Letchworth Garden City (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.

What we check on a supplied unit

A damaged delivery is a frequent snag on fit-only work. Before the day, unpack a loft roof window, photograph it, and tell the seller about any cracks or scuffs, because claims are much easier made early. We will also ask for the model or a link, so we can read the maker's instructions and check the opening size and the flashing kit it expects. If everything lines up, we fit it. If not, we explain what needs changing first.

Included in the work

  • Rafters trimmed and doubled where the openings need them
  • Linings fitted, ready for the plasterboarder or decorator
  • Underlay dressed and taped around every frame
  • Approved loft drawings — We work to the window positions on your approved loft drawings or agree changes with your builder first.
  • Combination flashings — We order combination flashings where windows sit close together.

From arrival to clean-up

On the day, you need to be in at the start and at the end. In between, the fitters get on with it. They will want the room below cleared where possible, a parking spot if you have one, and somewhere to set the unit down safely. After checking the opening and the upstand or flashing, they fix a loft roof window, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.

Planning, building control and Stevenage

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.

Help us quote accurately

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 SG1 and we will come back with a quote or a survey date.

Common questions in Stevenage

Do I need planning permission for a rooflight in Stevenage?

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.

Do you cover Stevenage?

Yes. Fitters travel to addresses in Stevenage and the surrounding districts, including SG1. We do not run an office there; the survey and the fitting happen at your property. A few island and remote postcodes are covered by arrangement; if yours is one, we confirm travel and dates before quoting.

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.
