How we handle construction mastic in Boarhunt
Site managers want applicators who turn up with the right cards and paperwork. We’re a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, and we are fully insured. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. We work on cladding and panel joints, floor and skirting junctions and internal decorators’ caulk, and the usual reasons a site gets in touch are frame gaps too wide for sealant alone and inconsistent sealant finishes from plot to plot. Whoever orders the work in Boarhunt, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Construction in and around smaller places such as Boarhunt 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 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:
- Frames fitted out of tolerance
- Faulty frames rather than failed sealant
- Designing joint widths or choosing the specification (that sits with the designer)
If you are not sure, just give us a call on 01277 525 020 or email the details over and we will give you a straight answer.

General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Cost factors for mastic packages
We price every job individually. The things that drive the figure:
- The size and state of each joint
- How accessible the joints are
- The site’s rules and procedures
- Specialist products, such as fire-rated or hygienic sealants
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.
Sending details for a quote
It doesn’t need to be a full survey. These details are enough to start:
- Approximate linear metres or a joint schedule
- What the building is and how it’s used
- Where the site is, with the postcode
- Specification clauses that apply
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email drawings and photos.
Signs you need construction mastic in Boarhunt
Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly.
Typical triggers for a call:
- Different trades sealing to different standards
- Oversized or tapered gaps around new frames
- Early adhesion failures on new external joints
- Missed perimeter joints on a new elevation
When units on a site such as Spurlings Industrial Estate (1.1 miles south-west of Boarhunt) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Before you book anyone

- How the existing material will be dealt with
- Their pre-qualification and accreditations
- Will RAMS and insurance details be available?

Boarhunt is within about 2 miles of the coast. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. Several hotels sit less than 2 miles from Boarhunt. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.
New wings at hospitals like Knowle Hospital, 2.9 miles west of Boarhunt, bring long runs of window and panel joints to seal. When a college such as Fareham College (to the south-west of Boarhunt) builds or refurbishes, the mastic package normally has to fit around students and staff.

On site: what to expect
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Jobs in and around smaller places like Boarhunt are usually planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- We start with the drawings, specification and programme.
- Quantities are measured and a fixed price returned.
- We agree with the site team which areas come first.
- Each area is sealed when it’s released.
- Joints are prepared, backed and sealed to the specification.
- After snagging, the work is handed over under our 12-month guarantee.
Getting the site ready
- Move anything stored against the joints
- For older buildings, check the asbestos register before work
- Arrange parking or a loading space
