From enquiry to sign-off
Tell us your site hours and access windows and we will plan around them. 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 Portswood is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out.
- The specified backing and sealant go in to depth and are finished neatly.

Fire stopping in Portswood, done properly
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 and the results are classified to BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. If you have fire stopping installed outside its tested range and fire sealant pulled out of the opening, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Portswood from the first photographs to the final walk-round, whether it’s one building or several.
Around smaller places like Portswood, 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.
We stand by our work with a 12-month guarantee. That covers our preparation and application.

Questions we are asked in Portswood
Can you work on a hospital site such as Royal South Hants Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
How does the move away from BS 476 affect penetration seals in Portswood?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Can the building stay open while you work?
In most cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
What do you charge?
It depends on the job: quantities, access, the product and any phasing. Call for a quote.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Leave it or put it right?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
Why appoint us
- Work carried out by CSCS-carded applicators
- Specification-led, product-correct work
- Fixed quotes based on photos, drawings or a visit
- 12-month guarantee on workmanship
Site staff or a sealant specialist?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
What affects the price in Portswood
What shapes the price:
- Specialist products, such as fire-rated or hygienic sealants
- Location, for remote and island sites
- The size and state of each joint
- Any access equipment needed
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
What we need to price the job
Good information means a firmer quote. Helpful details to send:
- Where the site is, with the postcode
- Access details, including height
- Specification clauses that apply
- Rough lengths or quantities, or drawings if you have them
To get a fixed quote, speak to us on 01277 525 020 or email the details over. You can also send details through our quote form.
Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- Arrange inspection before areas are covered up
- Look above ceilings when tiles are lifted for other jobs
- Settle who seals which penetrations at the start of a project
- Treat an open penetration as a priority repair
Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t.
Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned.
How the job changes by surface
Metal pipes
Heat travels along metal pipework. We follow whatever the detail requires and flag anything we can’t match.
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail, and we tell you if the bundle exceeds what sealant covers.
Compartment walls and floors in Portswood
Central London is about 69 miles from Portswood. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal. In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
On a hospital site such as Royal South Hants Hospital, 1 mile to the south of Portswood, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. Colleges such as Richard Taunton Sixth Form College, 1.1 miles to the west of Portswood, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. On a site such as Itchen Business Park, 0.5 miles north-east of Portswood, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.
