About our fire stopping in Colgate
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail rather than guesswork. Site teams most often ask us about fire-stopping items raised at inspection or handover and damaged fire seals in risers and voids, across linear gaps at wall heads, small duct penetrations where the tested detail allows and cable penetrations. For commercial sealant work in Colgate, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
For a smaller site near Colgate, we plan to do all the penetrations in one go, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Aftercare for building managers
A few simple habits keep the new joints working:
- Ask which product is in place before decorating
- Keep general-purpose fillers away from compartment walls
- Make fire stopping part of every scope that crosses a fire-resisting wall
- File the specified details where the next contractor can find them
Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t, so check the product data first.
Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open.
Diagnose, treat, sign off
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For work around Colgate, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Getting the site ready
- Send your site hours and access windows
- Move anything stored against the joints
- Let building users know which areas are affected

Why deal with it now?
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product. For buildings around smaller places like Colgate, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

FAQs: Colgate
Can you take on a job at a hospital such as Crawley Hospital?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Will you take on work at estates like Holmbush Potteries Industrial Estate, close to Colgate?
Yes. Our area takes in Colgate and its surroundings, with estates and business parks such as Holmbush Potteries Industrial Estate included. A few photographs and the unit address let us price the work.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
What does an EI 60 rating mean?
In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. An EI 60 seal kept its integrity and insulation for 60 minutes as tested and the installation has to match the test.
Do you work in Scotland as well as England?
Building standards in Scotland are separate from England’s, and England uses Approved Document B. Wherever the site is, our work follows the specification and the tested detail.
How much does the work cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

Common problems we fix in Colgate
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps. Linear joint details set a width range and movement capability, and the seal has to sit within them.
Common reasons buildings call us in:
- Unsealed openings around new pipes and cables
- Snag lists that include open service penetrations
- Builders’ foam or ordinary silicone in compartment walls
- Unsealed joints where partitions meet the slab
Halls and meeting rooms at places like St. Saviour's Church sometimes gain new services, and any compartment wall crossed needs the specified seal.
What your quote should include
- Can the work be phased to keep areas open?
- What site paperwork they can supply
- Whether primer will be used where the manufacturer specifies it
- Their pre-qualification and accreditations
Work for main contractors and building owners
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Service penetrations in Colgate buildings
Central London is about 30 miles from Colgate. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product. The 2 miles around Colgate include two care or nursing homes. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. We install fire-rated sealant to the tested detail where it is specified.
Hospital estates such as Crawley Hospital, 3.1 miles to the north-east of Colgate, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. On estates like Holmbush Potteries Industrial Estate (1 mile north of Colgate), the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
