Questions about Wentworth
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Wentworth?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Can you work around term dates at a campus such as Royal Holloway University?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, with one point of contact.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
What will the job cost?
We don’t publish prices, because every site is different. Send photographs or drawings and we will price it at a fixed figure.
How long does a typical visit take?
It depends on the scope, but the work normally takes anything from one day to a planned run of visits, depending on the number of seals and the access. For bigger or phased jobs, we will set out a timescale with the quote.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
About our fire stopping in Wentworth
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. 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. We work on small duct penetrations where the tested detail allows, cable penetrations and pipe penetrations, and the usual reasons a site gets in touch are hidden openings found during inspections and fire-stopping items raised at inspection or handover. Looking for mastic applicators who cover Wentworth? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
For a smaller site near Wentworth, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Owners, agents and contractors
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
How a job runs
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. For a building around Wentworth, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Preparing the site
- Let building users know which areas are affected
- Share the asbestos register for older buildings
- Point out parking and an unloading spot
Quotes
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

Fire stopping around Wentworth: what changes locally
Several hotels sit less than 2 miles from Wentworth. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
For a hospital such as St. Peter's Hospital, 3.3 miles south-east of Wentworth, penetration sealing is typically phased ward by ward, with infection-control rules agreed first. Hotels such as Wheatsheaf Hotel, 0.6 miles north of Wentworth, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.
Wentworth is about 3 miles south-west of Egham, in Surrey. Our applicators travel to Wentworth for work on service penetrations. Across Surrey, 379 places are covered, including Wentworth. We also cover Reading, around 17 miles from Wentworth.
Commercial sites across GU25 are covered. Among the streets we cover are London Road, Wentworth Drive and Portnall Rise. We also cover Virginia Water (1 mile east), Egham Wick (2 miles north), Stroude (2 miles north-east), Thorpe Green (2 miles east) and Englefield Green (2 miles north-east). Bigger towns within reach include Guildford (11 miles south), Woking (6 miles south), Camberley (7 miles south-west), Epsom (15 miles east), Ewell (15 miles east) and Egham (3 miles north-east).

What we can’t put right
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Large openings beyond what any sealant detail covers
- Deciding what a wall or floor needs, which belongs to the designer
- Signing off or certifying a building’s fire stopping
If you’re not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer before you book.
Where we work in Wentworth
- Pipe penetrations
- Service gaps in risers
- Linear gaps at wall heads
- Cable penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
Cost factors for service penetrations
Before we quote, we look at:
- Any access equipment needed
- The size and state of each joint
- Removal of failed or old sealant
- Induction, permit and paperwork requirements
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.
Before you send an enquiry
Whether it’s one area or a whole building, the same details help:
- Photos of the joints, close up and from further back
- The asbestos register, for older buildings
- Any dates the work must fit around
- Specification clauses that apply
For a fixed quote, speak to us on 01277 525 020 or email drawings and photos with the site address and an outline of the work. You can also send details through our quote form.
Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Check with the data sheet before painting over fire sealant
- Have penetrations checked while they can still be seen
- Ask the designer to confirm details early on refits
- Keep product data and details in the fire safety file
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, and the data sheet says which.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.
Do you need fire stopping in Wentworth?
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps, and the wrong product can split as a result. The tested detail for a linear joint states the width and movement it covers.
Common reasons buildings call us in:
- Unsealed penetrations discovered above suspended ceilings
- Fire-rated sealant that has cracked or shrunk back
- Service penetrations left open after M&E works
- Snag lists that include open service penetrations
At a college such as Strode's College, which lies north-east of Wentworth, checking penetration seals after summer M&E works is good practice.
