Fire stopping in Newnham
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
How the job changes by surface
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically, and note anything we find that isn’t on it.
Small ducts
Ducts are only sealed with sealant where the detail allows it. The ductwork, its supports and any dampers are for the ductwork contractor.
Fire stopping for commercial buildings in Newnham
We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control. What we bring is careful installation of the specified sealant, to the maker’s guidance. The enquiries we see most involve fire stopping installed outside its tested range and unsealed openings around new pipes and cables, across service gaps in risers, joints between fire-resisting walls and floors and linear gaps at wall heads. Searching for sealant specialists in Newnham? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Around smaller places like Newnham, 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.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Doing it in-house
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Compartments and services around Newnham
The area within 2 miles of Newnham holds a number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
Tenant changes at parks like Optrex Business Centre, 1 mile north of Newnham, bring new data and services, and openings through fire-resisting walls need the specified seal. Hotels like Basingstoke Country Hotel (to the south-east of Newnham) are refurbished in phases, and each phase can open up compartment walls. On a hospital site such as Basingstoke and North Hampshire Hospital, which lies west of Newnham, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
Newnham is about 5 miles east of Basingstoke, in Hampshire. Anywhere in RG27, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our Hampshire coverage takes in 723 places, from busy centres to rural villages. Reading is covered too, some 12 miles away.
Postcode districts covered here: RG27. Buildings on Tylney Lane, Newnham Lane and Ridge Lane are within our area for service penetrations. Just outside Newnham, we also work in Nately Scures (1 mile south), Hook Common (1 mile south-east), Up Nately (1 mile south), Hook (1 mile east) and Warnborough Green (2 miles south-east). Further afield, our area takes in Basingstoke (5 miles west), Farnborough (10 miles east), Fleet (7 miles east), Aldershot (10 miles east), Alton (9 miles south) and Yateley (8 miles north-east).

Work for main contractors and building owners
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Newnham can form part of a wider programme across Hampshire.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
What we can’t put right
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Reviewing a building’s overall fire safety
- Construction that lacks the fire resistance the seal relies on
If in doubt, give us a call on 01277 525 020 or email a schedule or drawings and we will say what we think before you book.
Where we work in Newnham
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Service gaps in risers

On site: what to expect
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Newnham are usually planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- 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.
- Unsuitable material is removed and the opening cleaned 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.
Getting the site ready
- Have the specification and drawings to hand
- Tell staff and tenants when we will be in
- Share the asbestos register for older buildings

Advice
FAQs: Newnham
Can you work on a hospital site such as Basingstoke and North Hampshire Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
What does the BS 476 change mean for fire-rated sealant in Newnham?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is 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.
Are you CHAS accredited?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Is any job too small?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Can you fit around our working hours?
Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
Why it’s worth doing now in Newnham
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme. For buildings around smaller places like Newnham, 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.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
