How we handle construction mastic in Picket Twenty
A typical mastic package covers more than window perimeters: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. One contractor for all of it keeps the responsibility in one place and gives you a consistent finish across the job. If you’re dealing with snag items on joints that need redoing before handover and existing joints on a refurb that need cutting out and resealing, we can put it right. For commercial sealant work in Picket Twenty, you deal with one contact from quote to sign-off, whether it’s one building or several.
Around smaller places like Picket Twenty, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Sites and facades in and around Picket Twenty
Picket Twenty sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack. Picket Twenty is about 62 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.
For contractors refurbishing units at places like Walworth Business Park (0.6 miles north of Picket Twenty), the mastic covers cladding panels, roller-door and window perimeters. When a college such as Andover College (1.4 miles west of Picket Twenty) builds or refurbishes, the mastic package typically has to fit around students and staff.
Picket Twenty is about 1 mile east of Andover, in Hampshire. Businesses, contractors and managing agents in Picket Twenty can call on us for mastic packages, as part of our coverage of Hampshire.

Honest limits
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Rework caused by others damaging completed areas
- Faulty frames rather than failed sealant
- Specifying the product where the designer hasn’t
If you’re not sure, just give us a call on 01277 525 020 or use the quote form and we will give you a straight answer.
Surfaces we seal
- Internal decorators’ caulk
- Window and door perimeters
- Brick and block movement joints
- Sanitary and kitchen joints
- Cladding and panel joints
- Floor and skirting junctions
After the work
Keep the joints in good shape with a few simple steps:
- Don’t force external sealing on a damp or frosty day
- Release areas for mastic once other trades have finished in them
- Brief the final clean team to avoid blades near sealant
- Put any product change through the designer first
If a joint is damaged after sealing, flag it early. Snags can be picked up in a planned close-out visit.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors, leaving the remedial work to the contractor. Getting the product and preparation right first time avoids that.
Different surfaces, different methods
Bathrooms, en suites and washrooms
On multi-unit schemes, consistency matters across hundreds of bathrooms. A single team keeps the standard consistent following the programme.
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, usually a low-modulus neutral-cure silicone and set the depth with backing where needed.
Signs you need construction mastic in Picket Twenty
On construction sites, joints typically fail early because of when they were sealed, not what was used. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, and the joint has to be redone.
If one of these sounds familiar, it’s time for a closer look:
- Inconsistent sealant finishes from plot to plot
- Cracks opening in caulked internal joints
- Sealant knocked or painted over by other trades
- A long mastic snag list close to completion
School extensions, at buildings such as Pilgrims' Cross CofE Aided Primary School, normally run to the summer holidays, mastic included.
What to look for in a quote
- Who will actually carry out the work
- Which product they’ll use, and why it suits the joint
- What the guarantee covers, and for how long
- Whether primer will be used where the manufacturer specifies it
