Fire rated sealant for homes and businesses in Palmers Green

Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we follow the tested detail for each one. We’re often asked to deal with linear gaps at the head of walls and fire stopping disturbed by later work, across door frames, flats & HMOs and service penetrations.

Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in Palmers Green, we agree timings and access before anything starts, and room-by-room programmes can be planned where needed.

All our work comes with a 12-month guarantee, wherever you are in Greater London.

How we quote for fire rated sealant

For a quick quote, just ask. The main things that affect it are:

  • How much old sealant there is and how hard it is to remove
  • The size of the job
  • Access and height
  • The number of rooms or windows

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

Helping us quote

To make quoting easier, let us know:

  • If someone has resealed it before
  • What the problem is, such as mould, gaps, leaks or cracking
  • The address or postcode of the job
  • Roughly how big the job is

There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To arrange one, phone 0345 464 0079 or send us an email.

What we do, step by step

A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. It generally takes a few hours for a handful of gaps, and longer for a whole building. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Palmers Green. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. We record the locations and products used for your records.

How to prepare

  • Move anything stored near the joints
  • Where the joints are inside, avoid wetting them before we arrive
  • Keep children and pets away from the work area

Getting a quote

Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand.

Workplaces and buildings in Palmers Green

There are hotels and other places to stay in and around Palmers Green. 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, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

For buildings such as Palmers Green United Reformed Church, gaps around pipes and cables are worth checking after any building work there. As a London address, Palmers Green can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you let a flat or house near Palmers Green station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.

Can you give us a record of the work?

Typically it takes a few hours for a handful of gaps, and longer for a whole building. Larger jobs naturally take longer, and we will tell you how long to expect.

When it is not the sealant

Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:

  • Sign-off of the building, which sits with building control or your assessor
  • Fire risk assessments, which need a qualified assessor
  • A wall that isn’t a fire-resisting element to begin with

If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before booking.

Surfaces we seal

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

What the job involves on each surface

Door frames

Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified.

Should I try it myself first?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Keeping the joints in good condition

No joint lasts for ever, but care makes a real difference. A few tips:

  • Include hidden areas like risers in routine checks
  • Check whether a sealant can be painted before decorating over it
  • Allow for resealing whenever new services are run
  • Keep the record of products and locations with your fire safety documents

Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. We can tell you which product we used.

A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so you can show it was dealt with.

Why act early in Palmers Green

Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.
