What the job involves on each surface

Linear gaps

Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both.

Plasterboard walls

In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.

About our fire rated sealant in Denton

Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through. If you have door frames with gaps between frame and wall and seals cut through by electricians, plumbers or data installers, we can put it right, on linear gaps, pipe & cable gaps and service penetrations alike.

If you have holiday lets, a converted barn used for business or a community building near Denton, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

When it isn’t the sealant

New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:

  • Deciding what fire stopping a building needs
  • Problems with the door itself rather than the gap around the frame
  • Walls or floors that weren’t built to resist fire

If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

Surfaces we seal

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

Fire rated sealant around Denton

Denton has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

For buildings such as Church of St Mary Magdalene, gaps around pipes and cables are worth checking after any building work there.

What affects the quote in Denton

You’ll get a clear quote before we start. It’s based on:

  • The number of rooms or windows
  • Whether old sealant or filler has to be cut out
  • Mould in or behind the old joints
  • When we can work, for business premises

Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

Asking for a quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • Pictures of the joints, sent by email
  • Whether it’s a home or a business
  • How we’d reach the joints
  • What the problem is, such as mould, gaps, leaks or cracking

Need a quote? Please call 0345 464 0079 or send us an email with a few details. You’ll know what we plan to do, and what it will cost, before any work begins.

DIY versus a professional finish

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Denton questions

Do you work for hotels and guest houses in Denton?

Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.

Do you cover smaller places like Denton?

Yes, Denton is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Do you seal gaps around fire door frames?

Yes. Gaps behind architraves are a common job for us. Doors, seals and closers need a door specialist.

What sealant do you use?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

How long will you be here?

That depends on how much there is to do, but most jobs take anything from a few hours to several days, depending on how many gaps there are. We will tell you when we quote.

Does someone need to be in?

It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.

Do you take out the old sealant first?

Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Do you certify the fire stopping?

We don’t certify fire stopping or quote ratings. We apply the specified product to the manufacturer’s details and list the locations and products for you.

How the visit works

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of gaps, and longer for a whole building. In a small place like Denton, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  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.

Getting ready for the visit

  • On commercial sites, let us know about site rules
  • Clear the area around the work
  • Try not to wet indoor joints just before the visit

What we are called out for in Denton

Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Damage from cleaning, knocks and maintenance adds to it.

People usually contact us when they notice one of these:

  • Gaps where walls meet ceilings or slabs
  • Unsealed gaps around fire door frames
  • Cracked or shrunken fire-rated sealant
  • Unsealed gaps where pipes and cables go through a wall

For landlords with property near Shepherds Well station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What your quote should include

  • Whether you can choose the colour
  • What product goes in the joint
  • Are they insured?
  • Who turns up on the day

Our hiring checklist

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Check whether a sealant can be painted before decorating over it
  • Do not fill fire-stopping gaps with ordinary foam or silicone
  • Keep the record of products and locations with your fire safety documents
  • Ask every contractor to reseal any fire stopping they disturb

Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.

Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.
