Your questions answered
Is Wessex Business Park, near Highbridge, within your area?
Yes. We cover Highbridge and the area around it, including industrial estates, business parks and retail parks such as Wessex Business Park. Photos and a short description are enough for a first look.
Is Highbridge too small for you to travel to?
No. Small places get the same service as large ones. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can the building stay open while you work?
In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
How much does the work cost?
Every job gets its own fixed quote. For yours, call the office on 01277 525 020 or email drawings and photos with a description of the work.
Can you send site paperwork?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
What hours do you work?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Construction mastic in Highbridge, done properly
Perimeter sealing outside needs a dry joint and the right temperature. Each sealant has a temperature range, and damp, frost or condensation on frames stops work so it helps to sequence elevations with some flexibility. Internal areas can typically carry on while the outside waits. Site teams most often ask us about failed sealant in an existing building being refurbished and a mastic package split between trades with no clear owner, across floor and skirting junctions, cladding and panel joints and sanitary and kitchen joints. Facilities teams, main contractors and managing agents in Highbridge tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Construction in and around smaller places such as Highbridge is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Maintenance after handover
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Note which sealant went where at handover
- Ask cleaners to use soft cloths around fresh sealant
- Ask for joint and product checks before the package is urgent
- Release areas for mastic once other trades have finished in them
Any damage after we have finished should go on the snag list straight away. Snags can be picked up in a planned close-out visit as agreed in the quote.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure so packing or adjustment by the installer comes first. We raise them during our first walk of the area.
Why deal with it now?
Some packages split mastic across the window fitter, kitchen fitter and plumber. In practice it often means different standards, gaps in responsibility and snags nobody owns. A single mastic package gives one point of responsibility and a consistent finish. Older rural buildings around Highbridge move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Related advice
For managing agents and facilities managers
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
We work for building owners and managing agents on everything from one building to a spread of sites around Highbridge. Several sites can go on one quote, which keeps the paperwork simple.
Surface by surface
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Joints are cleaned, sealed and tooled neatly.
Internal decorators’ caulk
Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s paintable and suits gaps that don’t move while moving joints need a flexible sealant.
Signs you need construction mastic in Highbridge
A new building moves while it dries and settles. Materials lose construction moisture and shrink. Choosing the right product for each joint reduces that.
Things that usually lead to an enquiry:
- Missed perimeter joints on a new elevation
- A long mastic snag list close to completion
- Cracks opening in caulked internal joints
- Existing joints on a refurb that need cutting out and resealing
For a contractor working at a hospital such as Wessex Hospital, which lies west of Highbridge, perimeter and facade sealing is planned around patients and deliveries.
