Fire stopping for commercial buildings in Hyde
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 small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and pipe penetrations, and what we’re called in for most is openings left by services added after handover and expanding foam used as fire stopping. Whoever orders the work in Hyde, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Converted and extended buildings around places like Hyde can mix old and new construction, so it’s worth confirming the wall or floor type before choosing the seal. The right product depends on the wall or floor and the services passing through, and we will tell you if the detail calls for something other than sealant.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Service penetrations in Hyde buildings
Hyde is about 60 miles 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. The 2 miles around Hyde include three care or nursing homes. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.
At a university such as University of Winchester, 0.9 miles to the south-west of Hyde, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. For a site team at a college like Peter Symonds College, 0.5 miles west of Hyde, fire-rated sealing is best scheduled after the summer works.
Hyde is about 1 mile north of Winchester, in Hampshire. Our applicators travel to Hyde for work on service penetrations, handled exactly as we handle every other area. Hyde is one of 723 places we cover in Hampshire. Sites around Southampton have their own page, about 11 miles away.
Business premises anywhere in SO23, SO22 and SO20 are within our area for service penetrations. Buildings on Elm Road, Swan Lane and City Road are within our area. We also cover Abbotts Barton (1 mile north-east), Winchester (1 mile south), Weeke (1 mile west), Highcliffe (1 mile south-east) and Bar End (1 mile south) for service penetrations. Bigger towns within reach include Eastleigh (7 miles south), Andover (12 miles north-west), Totton (13 miles south-west), Chandler's Ford (7 miles south-west), Hedge End (11 miles south) and Romsey (9 miles south-west).
What’s near Hyde
Locally, jobs take us to sites close to Peter Symonds College, Leigh House Hospital and The King Alfred pub. There’s a railway station in Hyde itself: Winchester station. A little further out are Winchester Castle (0.6 miles south-west) and Royal Observer Corps Museum (0.5 miles north). Green spaces nearby include Winnall Moors and Twyford Down.
Work for main contractors and building owners
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
Leave it or put it right?
Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down, and the right detail can be checked at the time. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

What affects the price in Hyde
The price varies from site to site. Expect it to depend on:
- How much there is to seal
- Any access equipment needed
- Distance, for remote addresses
- Specialist products, such as fire-rated or hygienic sealants
Pricing service penetrations depends on quantities, condition and access. Call for a quote.
Before you send an enquiry
The more we know, the firmer the quote. Helpful details to send:
- Any dates the work must fit around
- Anything awkward about access or site hours
- A wide shot and a close-up of the area
- Rough lengths or quantities, or drawings if you have them
A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or email the details over to discuss it first.
When to call us in Hyde
Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.
If one of these sounds familiar, it’s time for a closer look:
- Hidden openings found during inspections
- Fire sealant pulled out of the opening
- Fire seals cut back for extra cables and never reinstated
- Unsealed joints where partitions meet the slab
On a hospital site such as Royal Hampshire County Hospital, which lies south-west of Hyde, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
What your quote should include

- Proof of insurance
- How long is the guarantee, and what does it include?
Diagnose, treat, sign off
We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Work in places the size of Hyde is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Warn occupants and staff about the work
- Make sure the joints can be reached
- Flag any permit to work we will need

When something else is needed
We check first that sealant really is the fix. It won’t put right:
- Fire risk assessments, a job for a competent assessor
- Openings that need collars, wraps, batts or boards rather than sealant
- Gaps in walls that were never built as compartment walls
Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we’ll tell you honestly.
Where we work in Hyde
- Linear gaps at wall heads
- Service gaps in risers
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Joints between fire-resisting walls and floors
Common questions from Hyde clients
Do you seal service penetrations in hotels around Hyde?
Yes, where fire-rated sealant is the specified product. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.
Is Hyde too far out for you?
Not at all. Hyde is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
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, since fresh sealant will not bond reliably to aged material.
What about RAMS and site documents?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
