Why it’s worth doing now in Whiteley
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is normally a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Small buildings around Whiteley suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Fire stopping in Whiteley
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Other openings need collars, wraps, batts, pillows or boards. If the detail calls for something other than sealant, we say so rather than force sealant into it. We work on small duct penetrations where the tested detail allows, service gaps in risers and cable penetrations, and the failures we are asked to look at most are open linear gaps along the top of fire-resisting walls and unsealed openings around new pipes and cables. Most enquiries from Whiteley start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places like Whiteley, many commercial buildings are conversions or extensions of older ones, so the wall or floor a service passes through isn’t always what the drawings assume. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.

How the quote is worked out
We price every job individually. The main factors are:
- Whether old sealant has to be cut out first
- Joint width, depth and condition
- The product specified
- Any access equipment needed
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
What we need to price the job
A few photographs plus some basic facts will normally do. Please tell us:
- Whether the building will be occupied during the work
- Whether an asbestos survey exists
- The product your specification calls for
- When you need the work done
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to speak to us on 01277 525 020 or use the quote form.
Fire stopping in Whiteley: the local picture
A 2-mile radius around Whiteley takes in several hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
For a building at a site such as Solent Business Park, 0.6 miles south-east of Whiteley, a check of penetration seals after each fit-out is good practice. Halls and meeting rooms at places like St Margaret Mary sometimes gain new services, and any compartment wall crossed needs the specified seal.
Whiteley is about 3 miles south-east of Hedge End, in Hampshire. We cover Whiteley, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 723 places in Hampshire, from busy centres to rural villages. There’s a separate page for Southampton, about 6 miles away.

Advice
Common questions from Whiteley clients
Is Whiteley too small for you to travel to?
Not at all. Whiteley is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
What does the BS 476 change mean for fire-rated sealant in Whiteley?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure.
How do we ask for a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
What will the job cost?
That depends on the job: quantities, access, the product and any phasing. Call for a quote and we will price it properly.
What we are called out for in Whiteley
Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.
Site and facilities staff are often the first to spot these:
- Penetration schedules that need working through
- Builders’ foam or ordinary silicone in compartment walls
- Improvised or mixed-product fire seals
- Unsealed openings around new pipes and cables
For a hotel such as Solent Hotel and Spa, less than half a mile south-east of Whiteley, penetration seals are worth checking after any refit or services upgrade.
What to look for in a quote
- Will CSCS-carded applicators be on site?
- Whether primer will be used where the manufacturer specifies it
- Will RAMS and insurance details be available?
- The named product and why it was chosen
