Why act early in Hounsdown
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme, so earlier action pays back. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

Fire stopping for commercial buildings in Hounsdown
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. We work on joints between fire-resisting walls and floors, cable penetrations and small duct penetrations where the tested detail allows, and the failures we are asked to look at most are non-fire-rated filler around services and fire-stopping items raised at inspection or handover. Searching for sealant specialists in Hounsdown? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Around smaller places like Hounsdown, 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. The right product depends on the wall or floor and the services passing through, and we’ll tell you if the detail calls for something other than sealant.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Fire-rated sealing for Hounsdown buildings
Hounsdown has seven care or nursing homes no more than 2 miles away. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. We install fire-rated sealant to the tested detail where it is specified. For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. We install whatever has been specified, to the product’s tested detail.
Office fit-outs on sites such as Rushington Business Park (less than half a mile north of Hounsdown) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. Residences at universities like Southampton Solent University, 4.3 miles to the east of Hounsdown, have compartment walls that must be resealed whenever services change. Tenant changes at centres like Totton Shopping Centre, 1.1 miles north-east of Hounsdown, often mean new services through walls between units.

Hounsdown: questions and answers
Can you work around term dates at a campus such as Southampton Solent University?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is Hounsdown too far out for you?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
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.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Which standards are fire seals tested to?
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.
How many days will you need on site?
That varies with the scale of the job, but the work usually takes a single visit for a short list of penetrations, or a phased programme for a whole building. For bigger or phased jobs, we will set out a timescale with the quote.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Honest limits
Being straight saves everyone time. New sealant won’t cure:
- Approving the work on behalf of building control
- Gaps in walls that were never built as compartment walls
- Fire risk assessments, a job for a competent assessor
If you’re not sure, just ring 01277 525 020 or email the details over and we will give you a straight answer.

Advice
How the job changes by surface
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. The detail limits bundle size and the gaps between and around cables.
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed, and we work within it.
Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Looking after the joints
After handover, a little attention goes a long way:
- Foam or ordinary sealant is never a fire-seal repair
- Leave fire sealant to cure fully before covering it
- Include service cupboards in routine inspections
- Record which product was used where
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, so check the product data first.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open.
