What we’re called out for in Milton
When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.
Typical triggers for a call:
- Non-fire-rated filler around services
- Damaged fire seals in risers and voids
- Unsealed openings around new pipes and cables
- Old intumescent sealant that has split away
For a site team at a college like Portsmouth College, which lies north-east of Milton, fire-rated sealing is best scheduled after the summer works.
Before you book anyone
- Their plan for phasing and protecting the area
- Do they follow the manufacturer’s priming guidance?
- Are they CHAS accredited or on Constructionline?
- Will CSCS-carded applicators be on site?
Fire stopping in Milton, done properly
Most of our fire stopping work happens after the building is up. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls. We close the openings listed on your schedule, using the specified sealant and detail. If you have fire-stopping items raised at inspection or handover and openings left by services added after handover, we can put it right, on joints between fire-resisting walls and floors, service gaps in risers and cable penetrations alike. One point of contact handles commercial sealant work in Milton from the first photos to the final walk-round, whether it’s one building or several.
Converted and extended buildings around places like Milton can mix old and new construction, 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.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

When something else is needed
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Construction that lacks the fire resistance the seal relies on
- Large openings beyond what any sealant detail covers
- Deciding what a wall or floor needs, which belongs to the designer
If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think.
Surfaces we seal
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Cable penetrations
- Service gaps in risers
Cost factors for service penetrations
A fixed quote reflects the actual work. It allows for:
- Removal of failed or old sealant
- Access and working height
- Which sealant the job calls for
- How much there is to seal
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Sending details for a quote
To price the job accurately, we need to understand the site. Useful things to include:
- How the joints are reached, and at what height
- Your programme or deadline
- A wide shot and a close-up of the area
- Whether the building will be occupied during the work
The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or call the office on 01277 525 020 or send photos by email if you’d rather talk the job through.
Questions we are asked in Milton
Could you schedule work at a campus like University of Portsmouth for the vacation?
Yes. Education sites normally 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.
Would you work within a site like St James Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is sealant suitable for all service openings?
No. Each fire-rated sealant is tested for particular services, gap sizes and substrates. If an opening falls outside, it needs another solution.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Do you seal openings left by new services?
Yes, provided a specification covers them. Openings left by new services are among the most common jobs we see and we close them with the specified product.
What about RAMS and site documents?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
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’ll set out a timescale with the quote.
Owners, agents and contractors
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.
Different surfaces, different methods
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Larger or fire-rated ductwork typically needs a different solution set by the designer.
Drylining partitions
Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers before sealing.
Our process
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 typically taking a single visit for a short list of penetrations, or a phased programme for a whole building. For a site in Milton, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Before we start on site
- Point out parking and an unloading spot
- Share your working hours and any access restrictions
- Let us know about inductions and permits
Getting a fixed quote
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.
