How we handle fire rated sealant in Patching

Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it. If you have old fire sealant that has split or come away and gaps filled with a product that isn’t fire-rated, we can help, on door frames, pipe & cable gaps and service penetrations alike.

If you run a pub, café, guest house or shop in or near Patching, its washrooms and kitchen need the same sealant care as any big building.

There’s a 12-month guarantee on every job, large or small.

Commercial buildings in Patching

Patching has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.

If you let a flat or house near Chelmsford station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Surface by surface

Linear gaps

Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run leaving no stretch unsealed.

Flats and HMOs

Working in occupied flats needs some planning. We agree access to each flat and the common parts before work begins to keep disruption down.

Patching questions

Can you help a landlord with a rental near Chelmsford station?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.

Will you come out to Patching?

Yes. Patching is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

What do you put in the joint?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.

Where do you work from?

We work from Crawley. Our applicators cover Patching.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Can you do several jobs on one visit?

Yes. Just list everything you need and you’ll get one quote.

Do you guarantee your work?

Yes. There’s a 12-month guarantee on every job.

Can you work in occupied buildings?

Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we will plan the work to suit.

What we cannot put right

Before booking, it’s worth knowing the limits:

  • Fire risk assessments, which need a qualified assessor
  • Problems with the door itself rather than the gap around the frame
  • Sign-off of the building, which sits with building control or your assessor

If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before you book.

What we seal

  • Linear gaps
  • Pipe & cable gaps
  • Flats & HMOs
  • Plasterboard & masonry
  • Door frames
  • Service penetrations

DIY sealant or a professional job?

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

What we’re called out for in Patching

Buildings are refitted and reconfigured over the years. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.

These are the problems we are asked about most:

  • Ordinary sealant used where a fire-rated product was needed
  • Joints picked up in a fire-stopping survey
  • Linear gaps at the head of walls
  • Open gaps behind door architraves

Managing a site like St John Payne Catholic School? Then service openings in fire-resisting walls need checking after any refurbishment.

How to choose a mastic man

The process

A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes a few hours for a handful of gaps, and longer for a whole building. Parking around Patching is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  1. Access to each area is agreed so the work can run in order.
  2. Old, damaged or unsuitable sealant is removed.
  3. Dust and loose debris are cleaned from each gap.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. We record what was done and flag anything that needs a different system.

Before we arrive

  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention if the joints have been sealed before
  • Where the joints are inside, avoid wetting them before we arrive

Related advice

Why deal with it now?

Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own. Homes in smaller places like Patching can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will explain what it covers.
