Trusted fire rated sealant in Stanton Harcourt

Fire rated sealant for homes and businesses in Stanton Harcourt

Deciding which gaps need fire stopping is not our role; your assessor, designer or building control sets that out. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We work on plasterboard & masonry, linear gaps and service penetrations, and common reasons people get in touch are fire seals that have cracked with movement and unsealed gaps around fire door frames.

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

A 12-month guarantee comes as standard.

When it isn’t the sealant

In fairness, there are a few things sealant will not fix:

  • Openings too large for sealant, which need batts, boards or another system
  • A wall that is not a fire-resisting element to begin with
  • Sign-off of the building, which sits with building control or your assessor

If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.

Quotes for fire rated sealant in Stanton Harcourt

There’s no set price list, because jobs vary so much. The quote depends on:

  • The product the joint needs
  • Whether old sealant or filler has to be cut out
  • How easy the joints are to reach
  • How many areas need sealing

The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

What to tell us for a quote

To make quoting easier, please include:

  • If it’s domestic, commercial or a hotel
  • How we’d reach the joints
  • Photos by email, if that’s easy
  • Roughly how big the job is

Every job is quoted individually. Simply phone 0345 464 0079 or email us and describe the job and send pictures if you have them.

DIY versus a professional finish

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What the job involves on each surface

Door frames

Frame gaps are normally hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size.

Linear gaps

Gaps along the top of partitions are easy to miss above a ceiling. We seal them along their full length leaving no stretch unsealed.

How it works

When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on how many gaps there are. In a small place like Stanton Harcourt, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. We measure every gap and note what it’s in and what passes through.
  3. Any non-fire-rated filler is removed and the gap cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. Every location is recorded with the product used.

Before we arrive

  • Mention if the joints have been sealed before
  • For indoor joints, keep the area dry beforehand if you can
  • Mention any leaks or damp you’ve noticed

Workplaces and buildings in Stanton Harcourt

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Schools such as Stanton Harcourt CofE Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. If you look after a church, hall or community building such as Church of St Michael, service openings in its walls need the right fire-rated sealant, as in any building.

How to look after the new joints

Aftercare is simple:

  • Tell trades working in the building that fire seals must be put back
  • Include hidden areas like risers in routine checks
  • Allow for resealing whenever new services are run
  • Flag any open gap you spot round a pipe or cable

Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.
