Fire rated sealant in Boxted, done properly
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. We work on linear gaps, pipe & cable gaps and flats & HMOs, and people most often call us about old fire sealant that has split or come away and sealant items on a fire risk assessment action list.
Work in a small place like Boxted is planned ahead, journey included, so it can be fitted around guests, customers or events where possible.
Each job carries a 12-month guarantee, whatever its size.

What fire rated sealant looks like in Boxted
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.
If you look after a church, hall or community building such as Church of St Peter, older buildings that have had new heating or wiring often have service gaps worth checking. For landlords with property near Colchester station, any gap left by new services in shared walls should be closed with a fire-rated product. For site and facilities teams at buildings such as Boxted St Peter's Church of England School, fire-stopping around service openings should be restored whenever new services go in.

What happens if it’s left?
Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. In a small place like Boxted, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.

What the job involves on each surface
Door frames
A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. We seal it with a product tested for that service and gap size.
For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.

How we quote for fire rated sealant
Call for a quick quote. The main things that affect it are:
- Working hours on commercial sites
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
- Which sealant suits the joint
Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- If someone has resealed it before
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
- Roughly how big the job is
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or drop us an email.
How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on how many gaps there are, and the area is left clean. In a small place like Boxted, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We plan the order of work and access, floor by floor or flat by flat.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Getting ready for the visit
- Tell us if parking is tricky
- Let us know if you’ve seen damp or leaks

Advice
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
When something else is needed
A few problems are outside what sealant work can do:
- Large holes that need a different fire-stopping system
- Deciding what fire stopping a building needs
- Fire doors that need new seals, closers or hardware
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.
