What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It won’t put right:
- Approving the work on behalf of building control
- Fire doors, dampers or other fire safety equipment
- Writing the fire-stopping specification
If in doubt, speak to us on 01277 525 020 or email us and we will say what we think.
Joints and surfaces we work on
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Service gaps in risers
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
Fire stopping in Hook Park Estate, done properly
Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it using the product and detail it sets out. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you have seals that don’t match their tested detail and fire-rated sealant that has cracked or shrunk back, we can help, on joints between fire-resisting walls and floors, linear gaps at wall heads and cable penetrations alike. Whoever orders the work in Hook Park Estate, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Around smaller places like Hook Park Estate, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
A 12-month guarantee applies to all our work in Hampshire. Should something we installed fail, call the office on 01277 525 020 or email us and we will come back to it.

Different surfaces, different methods
Drylining partitions
Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers before sealing.
Linear joints
Joints at the top of partitions may need to move as the slab above deflects. The specified product and backing for that movement are what goes in, along the full length of the run.
Diagnose, treat, sign off
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking anything from one day to a planned run of visits, depending on the number of seals and the access. Smaller jobs around Hook Park Estate can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.
- The specification and schedule come first, so we know which details apply.

What happens if it’s left?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. For buildings around smaller places like Hook Park Estate, 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.
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

Where services cross fire walls in Hook Park Estate
Hook Park Estate lies roughly 69 miles out from central London. 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. For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. Our part stays the same: the specified product, installed to its tested detail.
Holiday works at schools like Hook-With-Warsash Church of England Academy often leave service openings to seal before pupils return. In a building such as Church of St Mary, any service penetration through a fire-resisting wall should be sealed to the specified detail. Hospital estates such as Fareham Community Hospital (2.2 miles north of Hook Park Estate) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

Site staff or a sealant specialist?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
FAQs: Hook Park Estate
Is Hook Park Estate too far out for you?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Is a hospital such as Fareham Community Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How long does a job like this take?
That varies with the scale of the job, though a typical visit usually takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For bigger or phased jobs, we will set out a timescale with the quote.
What site paperwork can you supply?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Can the sealant be colour-matched?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Looking after the joints
A few simple habits keep the new joints working:
- Settle who seals which penetrations at the start of a project
- File the specified details where the next contractor can find them
- Look above ceilings when tiles are lifted for other jobs
- Check with the data sheet before painting over fire sealant
Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate.
