What the job involves on each surface
Fire-rated seals where specified
Fire-rated sealant is only one type of fire-stopping product. Other products, such as collars, wraps and batts, are specified for different services, so we will flag it if the detail needs a different product.
Facade and cladding joints
Facade sealant failures can be hard to spot from the ground. Close-up photos or a site visit tell us what’s needed.
Sealant applicators in Newtown
A reseal stands or falls on the preparation underneath it. Old silicone gives new sealant nothing to grip, so every trace of it is removed. Primer is used wherever the manufacturer calls for it on that surface. If you have greasy, split joints in a kitchen or tea point and wall and floor joints that have lost their seal, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Newtown is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In an occupied building in Newtown, the job is planned so areas stay in use: we agree the order with you and hand back each area with its cure time.
In and around smaller places such as Newtown, the commercial buildings we’re asked about are often pubs, shops, village halls and barns converted to offices. Each has kitchens, washrooms and frames whose joints need renewing in time.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or send details through our quote form and we will come back to it.

Questions about Newtown
Do you offer colour-matched sealant for buildings in Newtown?
Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Send colour references or photographs and we’ll confirm what’s available for the product.
Is a smaller place like Newtown outside your area?
Not at all. Newtown is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Do you work for facilities managers and managing agents?
Yes. You can send details through our quote form.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
How do we get a quote?
Start with whatever information is to hand. Questions or a site visit follow where needed, then a fixed quote.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

- Photos of the joints, close up and from further back

When to call us in Newtown
The wrong sealant in the wrong place is a common cause of early failure. Decorators’ caulk on a joint that moves, acetoxy silicone on stone or metal, or a stiff sealant on a facade. BS 6213 gives guidance on choosing construction sealants, and many specifications refer to it.
Things that normally lead to an enquiry:
- Layers of sealant, all of them failing
- External beads that have gone brittle and cracked
- Damp patches where an external joint has failed
- Frame sealant that has cracked, shrunk or pulled away
If you run an office at a site such as Waltham Business Park, which lies north-west of Newtown, the sealant at reception desks, tea points and frames ages with each fit-out.
What your quote should include
- The named product and why it was chosen
- Health and safety accreditation such as CHAS
- What level of public liability insurance do they hold?
- Will CSCS-carded applicators be on site?
For managing agents and facilities managers
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Newtown can form part of a wider programme across Hampshire.
Sealant on show in Newtown’s commercial buildings
Newtown has two named business or industrial parks inside a 3-mile radius. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints. The South East is one of the drier parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.
If you have premises on more than one site, say at Waltham Business Park and Parklands Business Park, one contractor and one quote can cover both. For premises near Portchester station, 4.4 miles to the south of Newtown, footfall is part of the plan: work is phased so shops and offices keep trading.
Newtown is about 5 miles north-west of Waterlooville, in Hampshire.

What’s near Newtown

Why deal with it now?
Leaving a failed joint rarely saves money. Once water gets behind the seal, finishes and ceilings underneath are next, and the bill then involves other trades. Dealing with it while the damage stops at the bead is the cheaper route. Halls, stores and units around places like Newtown may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.
