Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What sets the cost
Quotes vary with the job. Expect it to depend on:
- Removal of failed or old sealant
- The size and state of each joint
- How much there is to seal
- Working within restricted access windows
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
Before you send an enquiry
We can often quote from photographs and a few details. It helps to include:
- The site address and postcode
- A wide shot and a close-up of the area
- Rough lengths or quantities, or drawings if you have them
- Any dates the work must fit around
Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. For a chat about it beforehand, ring 01277 525 020 or email drawings and photos.
About our construction mastic in Fontwell
The specification and the programme set the job rather than whatever product is to hand. Where the specification names a product, we use it, and if an alternative is proposed, it goes to you for acceptance first. Joint widths, backing, primers and tooling follow the manufacturer’s guidance. If you’re dealing with frame perimeters left unsealed or poorly sealed and early adhesion failures on new external joints, we can put it right. For commercial sealant work in Fontwell, you deal with one contact from quote to sign-off, whether it’s one building or several.
Construction in and around smaller places such as Fontwell is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Common questions from Fontwell clients
Can you work at a site such as Tokar Industrial Park, by Fontwell?
Yes. Our area takes in Fontwell and its surroundings, with estates and business parks such as Tokar Industrial Park included. Photos and a short description are enough for a first look.
Could you schedule work at a campus like University of Chichester for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Are you insured?
Yes. We’re fully insured, and the certificate can go with your quote.
Do you install fire-rated sealant as part of a package?
Where it’s specified, yes, working to the specification and the manufacturer’s installation guidance. We’ll flag if the detail needs a different product.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, 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.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Common problems we fix in Fontwell
Shrinkage and settlement in the first months put new joints under strain. Plaster, screeds, timber and blockwork all shrink as they lose moisture and internal caulk in a moving joint is normally the first to crack. Choosing the right product for each joint reduces that.
These are often picked up first by site or facilities staff:
- Mastic snags holding up handover
- External joints sealed in damp or cold conditions that are now failing
- Oversized or tapered gaps around new frames
- Internal caulk splitting as the building dries out
Hospital estates such as Arundel and District Hospital, 3.7 miles to the east of Fontwell, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Facades, frames and programmes in Fontwell
Fontwell is about 51 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.
When a school such as Ormiston Six Villages Academy is extended or refurbished, the mastic package is often squeezed into the holidays. When units on a site such as Tokar Industrial Park, 1.8 miles south-east of Fontwell, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Fontwell is about 5 miles north of Bognor Regis, in West Sussex. Anywhere in BN18, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee.

Advice
Honest limits
We check first that sealant really is the fix. It won’t put right:
- Joints damaged after sign-off by following trades
- Glazing units that are cracked or misted
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we will tell you honestly before you book.
Surfaces we seal
