Smoke vent rooflight installation in Hounslow

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 smoke vent rooflight installation in Hounslow, internal finishing is listed so you can see whether it is included or left for your decorator. That way a smoke vent rooflight looks right from the room below as well as from outside. We cover Hounslow and properties throughout Greater London.

Fitting across Hounslow and nearby

Looking at a property near Hounslow but not quite in it? We work across TW3, TW4 and TW5 and outwards to Isleworth, Heston and Twickenham. 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 Hounslow.

What the job includes

  • Old vent removed with the stairwell kept protected below
  • New vent fitted, sealed and weathered into the roof
  • Commissioning and sign-off carried out by the specialist before handover
  • Free area at the stair head — We check the free area the vent must provide before choosing a replacement.
  • Upstand and weathering — We check the upstand suits the new vent and that the roof around it is sound.

How a fitting day runs

Fitting days start with a look at the sky. If rain is due, the order of work changes so the roof is never left open to it. A typical day for a smoke vent rooflight runs like this: set up access, protect the room, open up the roof or prepare the existing kerb or frame, check sizes, fix, seal, then finish inside. On jobs that take more than a day, the opening is weather-sealed overnight. The last hour goes on tidying, waste removal and a walk-round with you.

Regulations for Hounslow properties

A replacement smoke vent in England has to keep the free area and performance the building's fire strategy relies on, using a vent certified to BS EN 12101-2 with its actuator and backup power. We fit the vent and do the roof work; a smoke-control specialist connects and commissions the controls, and we confirm whether building control needs to be notified.

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 TW3 and we will come back with a quote or a survey date.

Common questions in Hounslow

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.

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.

What if my roof opening is the wrong size for the smoke vent 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.
