Walk-on rooflight installation in Durham

A rooflight is not finished when the roof is watertight. The inside matters too: the reveal or lining around the opening, the plaster, the trim where it meets the ceiling. Some installers leave that for somebody else. When we quote for walk-on rooflight installation in Durham, internal finishing is listed so you can see whether it is included or left for your decorator. That way a walk-on rooflight looks right from the room below as well as from outside. We cover Durham and properties throughout County Durham.

Fitting across Durham and nearby

Jobs across DH1, DH7 and DH6 are part of our normal cover for Durham. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Spennymoor and Chester-le-Street are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

Buying your own, or letting us supply

There are two ways to do this. Supply and fit means we source a walk-on rooflight that suits your roof and install it, so one company answers for both the product choice and the fitting. Fit-only means you buy the unit and we install it. With fit-only, the product warranty stays with the maker or seller, and our written guarantee covers the fitting work. Both routes get the same checks on the opening, the upstand and the maker's instructions before anything is fixed.

What we do on the day

  • Drainage around the unit checked so water does not lie on the glass
  • Unit bedded and fixed so it sits level with the finished surface
  • Perimeter joints sealed and the waterproofing lapped as the maker shows
  • Structural calculations — We need structural calculations for the glass and its support before a walk-on job goes ahead.
  • Weight on delivery day — We plan the delivery and lift before booking any lifting gear or extra hands.

How a fitting day runs

Morning first: the team arrives, introduces itself and walks through the job with you. Dust sheets go down in the room below and along the route in. Then the opening and upstand, or the flashing on a pitched roof, are checked against the unit's measurements. A walk-on rooflight goes in, is fixed to the maker's pattern and sealed into the roof covering. Inside, the reveal is finished as quoted. Before leaving, the team clears debris and talks you through what was done. Most jobs of this type take one to two days.

Do you need permission in Durham?

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

Keep it simple. Two or three photos, outside and inside. Approximate sizes. What the roof is made of. Anything awkward about getting up there, such as a conservatory below, a narrow side path or no parking. If you bought the rooflight online, the link or model name. Then your postcode in or around DH1. That is enough for a first price.

Common questions in Durham

What if my roof opening is the wrong size for the walk-on rooflight?

We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.

Do you make good inside after fitting?

Yes, where the quote includes it. Internal finishing usually means lining the reveal with plasterboard, taping or skimming, and fitting trim where it meets the ceiling. Some people prefer their own plasterer or decorator to finish off, which is fine. The written quote spells out exactly where our work stops, so nobody is left guessing about who does what once the unit is in.

How does payment work?

Payment terms are set out on your written quote before you accept it. Depending on the job, that may mean a deposit, stage payments for larger work, or payment on completion. The contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group. Nothing is added without your agreement: if something unexpected comes up, we discuss it and agree any change before carrying on.
