Construction mastic for South Hayling sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
What happens if it’s left?
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. If the frame is in good order, cutting out and resealing the perimeter can be all it needs, which is a much smaller cost. We’ll say so if a frame itself is the problem. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

Construction mastic in South Hayling
The programme rarely stands still, so the mastic package has to flex with it. We agree a sequence at the start and adjust it as the site manager releases areas and we don’t seal before other trades have finished in an area. That keeps the work right first time and saves rework. If you’re dealing with perimeter gaps outside the sealant’s range and inconsistent sealant finishes from plot to plot, we can put it right, on floor and skirting junctions, sanitary and kitchen joints and brick and block movement joints alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in South Hayling it comes down to the same thing: the right product in a properly prepared joint.
Conversions around smaller places like South Hayling often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.
Every job we finish is backed by a 12-month workmanship guarantee, in South Hayling as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Building and refurbishing in South Hayling
The sea is no more than about 1 mile from South Hayling. 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. South Hayling has several hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
University estates such as University of Portsmouth - Langstone Campus (2.9 miles west of South Hayling) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. For contractors at a school such as Mengham Junior School, sealing has to be finished before term starts. Hotel extensions and refits, at places such as Newton House Hotel (0.6 miles north-west of South Hayling), typically run between busy periods, so the sealing is squeezed into short windows.
South Hayling is about 5 miles east of Portsmouth, in Hampshire. South Hayling sits inside our coverage and the rest of Hampshire, with the same fixed quotes and 12-month guarantee as everywhere else. South Hayling is one of 723 places in Hampshire on our list.

Your questions answered
Will you plan work around the academic year at somewhere like University of Portsmouth - Langstone Campus?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you take on work at healthcare sites like St James Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Is colour matching possible?
It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
When can the area be used after sealing?
We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
What will the job cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.
Will you stick to the specified products?
Specification first, then the maker’s instructions. Preparation, backing and depth follow the product guidance.
What we can’t put right
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Frame gaps too wide for sealant, which the installer needs to correct
- Rework caused by others damaging completed areas
If in doubt, call 01277 525 020 or use the quote form and we’ll say what we think.
Joints and surfaces we work on
- Internal decorators’ caulk
- Window and door perimeters
- Cladding and panel joints
- Floor and skirting junctions
- Sanitary and kitchen joints
- Brick and block movement joints
Different surfaces, different methods
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Each joint is prepared, sealed and finished with a neat tooled line and baths are loaded where appropriate before sealing.
External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. Depth is controlled with backing rod so the bead bonds to two sides only.
After the work
For the best life from the joints:
- Brief following trades on areas that have been sealed
- Get the mastic subcontractor involved early in the programme
- Brief the final clean team to avoid blades near sealant
- Don’t schedule sealing before decorators and flooring are done
Once an area is sealed, protect it from following trades. New beads should be left to cure before cleaning or decorating nearby, and that time depends on the product, temperature and joint depth.
Oversized gaps are a problem better caught early. Sealant stretched over an oversized gap won’t last so packing or adjustment by the installer comes first. We raise them during our first walk of the area.
Diagnose, treat, sign off
Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. What matters most for a job in South Hayling is a clear list of what needs doing, so send photographs of each area. You will then get a fixed price for the work.

- We take off quantities and return a fixed quote.
- The sequence is agreed with the site manager.

Doing it in-house
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
