Construction mastic in Penton Corner, done properly
A typical mastic package covers more than window perimeters: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. Splitting those between trades often leaves gaps in responsibility and gives you a consistent finish across the job. If you have cracks opening in caulked internal joints and snag items on joints that need redoing before handover, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Penton Corner tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In the countryside around places like Penton Corner, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Common problems we fix in Penton Corner
On a live site, contamination is the biggest threat to a new joint. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond.
Site and facilities staff are often the first to spot these:
- Frame gaps too wide for sealant alone
- Frame perimeters left unsealed or poorly sealed
- Caulk cracking where joints are moving more than expected
- Failed sealant in an existing building being refurbished
For contractors at a college like Andover College (2 miles east of Penton Corner), perimeters and internal sealant are timed for the holidays.
Questions to ask before you book
- Health and safety accreditation such as CHAS
- Proof of insurance
- How the joint faces will be prepared and primed
- What the guarantee covers, and for how long
New build and refits around Penton Corner
Penton Corner is about 65 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme. Penton Corner is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager.
When units on a site such as Plot 2 Andover Business Park (to the south-east of Penton Corner) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Extensions at sites like Andover War Memorial Hospital (1.5 miles east of Penton Corner) typically sit beside working departments, and the mastic follows strict access rules.

Different surfaces, different methods
Window and door perimeters
Perimeter joints between frames and the structure are the weather line on any new building. We use the specified perimeter sealant, normally a low-modulus neutral-cure silicone.
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Joints are cleaned, sealed and tooled neatly.
On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly.

Advice

Do you take on small jobs?

Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

It depends on the scope, but the work typically takes as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Cost factors for mastic packages
Your fixed quote is built from the real scope. It takes account of:
- Whether old sealant has to be cut out first
- Travel to remote or island sites
- How accessible the joints are
- Which sealant the job calls for
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
What we need to price the job
Whether it’s one area or a whole building, the same details help:
- Access details, including height
- Approximate linear metres or a joint schedule
- Any dates the work must fit around
- The postcode of the building
Let us know the site, the scope and your timescale, and we will put a fixed quote together. The easiest way is to ring 01277 525 020 or email the details over.
Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Don’t force external sealing on a damp or frosty day
- Check frame gaps are within the sealant’s range before sealing
- Note which sealant went where at handover
- Don’t schedule sealing before decorators and flooring are done
Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead, so stick to soft cloths and gentle cleaners near sealant.
Sanitary joints that fail early become defects soon after occupation. Water gets behind trays, vanity tops and panels, leaving the remedial work to the contractor. Proper preparation, with the right silicone first time, keeps it off the defects list.
