Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.
How we handle fire stopping in Arborfield
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on cable penetrations, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows, and what we are called in for most is open linear gaps along the top of fire-resisting walls and fire seals cut back for extra cables and never reinstated. Searching for sealant specialists in Arborfield? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Rural conversions around Arborfield can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Service penetrations in Arborfield buildings
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail. Central London is about 36 miles from Arborfield. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
On a site such as Thames Valley Science Park, 1.4 miles north-west of Arborfield, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. Campus buildings at universities such as University of Reading - Whiteknights Campus (2.9 miles north-west of Arborfield) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. Wherever services are added at a hospital such as Wokingham Hospital (3 miles east of Arborfield) the compartment line has to be made good with the specified product.
Arborfield is about 3 miles west of Wokingham, in Wokingham. We send applicators to Arborfield for service penetrations. We work across 42 places in Wokingham, large and small.

From enquiry to sign-off
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Arborfield, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.

Leave it or put it right?
Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed, so earlier action pays back. Converted and older buildings near places like Arborfield tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

How the job changes by surface
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically, and note anything we find that isn’t on it.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on and we confirm each before sealing.
Questions about Arborfield
Can work at a site such as University of Reading - Whiteknights Campus fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
How does the move away from BS 476 affect penetration seals in Arborfield?
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 to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Do you offer coloured sealant?
It depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Are you insured?
Yes. We are fully insured, including public liability cover.
Can the building stay open while you work?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
Looking after the joints
After handover, a little attention goes a long way:
- File the specified details where the next contractor can find them
- Settle who seals which penetrations at the start of a project
- Get seals inspected before ceilings and boxing close
- Check risers and ceiling voids after each round of works
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original, or a new specification from the designer.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job; found late, it can be one of many.
General trades versus a specialist
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
