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, with the same standard on every plot. For buildings around smaller places like West Thorney, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

How we handle construction mastic in West Thorney
Since 2005 we have worked alongside main contractors, developers and fit-out firms. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. For construction mastic on a scheme in West Thorney, send drawings through our quote form, or phone or email us to talk it through. We work on sanitary and kitchen joints, cladding and panel joints and brick and block movement joints, and the usual reasons a site gets in touch are existing joints on a refurb that need cutting out and resealing and mastic snags holding up handover. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in West Thorney it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In the countryside around places like West Thorney, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Our workmanship is guaranteed for 12 months, in West Thorney as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Keeping the joints sound
Cleaning and maintenance staff play a part too. Share these points with them:
- Keep finished joints away from paint, plaster and scrapers
- Ask installers to correct oversized gaps first
- Record the products used in the O&M file
- Use the product the specification names
The package carries our 12-month guarantee for workmanship. Damage by others isn’t a workmanship fault, so protecting sealed areas matters.
Leaving the mastic snag list to the end squeezes everyone. A planned close-out through each area as it completes keeps the list short and keeps handover on track.
Your questions answered
Can you work on a hospital site such as Havant War Memorial Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does the sea air around West Thorney change the choice of sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Do you have public liability insurance?
Yes. We’re fully insured, including public liability cover.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Do you use the sealant named in the specification?
We follow the specified sealant, and we’ll raise it if something in it doesn’t suit the joint. Product standards such as BS EN 15651 are often named in specifications.
How do you work with the site programme?
We follow the trades through the building. Each plot, floor or elevation is sealed when it’s ready, and we will raise anything that holds the work up.
On site: what to expect
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Jobs in and around smaller places like West Thorney are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- We seal plot by plot or floor by floor in line with the programme.
- Any frame gaps or issues outside our scope are flagged to the site team.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Getting the site ready
- Tell us what induction or permit system the site runs
- Confirm the product named in the specification
- Arrange parking or a loading space
Getting a fixed quote
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Contractors’ notes for West Thorney
West Thorney is within about 1 mile of the coast. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.
Extensions at sites like Havant War Memorial Hospital (4.3 miles north-west of West Thorney) typically sit beside working departments, and the mastic follows strict access rules. Older buildings in the area around West Thorney, such as Warblington Castle (3.1 miles north-west of West Thorney), need care when sealed: the product has to suit soft or historic materials. When units on a site such as Finchwood Farm Industrial Estate, 2.5 miles west of West Thorney, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
West Thorney is about 5 miles south-east of Havant, in West Sussex. We send applicators to West Thorney for mastic packages, handled exactly as we handle every other area.

How the quote is worked out
Your fixed quote is built from the real scope. It allows for:
- Distance, for remote addresses
- Whether the work must be split into stages
- Backing rod, priming and other preparation
- Quantities, in metres or numbers
A quote for mastic packages depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
Before you send an enquiry
We can often quote from photographs and a few details. It helps to include:
- Any dates the work must fit around
- Whether the building will be occupied during the work
- Where the site is, with the postcode
- Specification clauses that apply
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call 01277 525 020 or send details through our quote form with what you know.
Honest limits
Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:
- Approving fire stopping as compliant
- Joint design decisions that belong to the architect or engineer
- Rework caused by others damaging completed areas
If in doubt, call the office on 01277 525 020 or use the quote form and we’ll say what we think before you book.
Joints and surfaces we work on

Owners, agents and contractors
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
