Construction mastic in Charter Alley
Most of the packages we price run well beyond frames: 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 perimeter gaps outside the sealant’s range and snag items on joints that need redoing before handover, we can put it right, whatever the surface. A single leaking joint is often how a building in Charter Alley first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Construction in and around smaller places such as Charter Alley is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Surface by surface
Kitchens and utility areas
On commercial kitchen fit-outs, hygienic sealants are often specified. We follow the specification and seal to a smooth, cleanable finish.
Window and door perimeters
Gaps around frames have to be within the sealant’s range. We check them during the first walk-round and flag any that need packing or adjusting before sealing starts.
Maintenance after handover
A few simple habits keep the new joints working:
- Ask cleaners to use soft cloths around fresh sealant
- Put any product change through the designer first
- Share drawings and the specification as soon as possible
- Flag uneven or tapered frame gaps early
After we’ve sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby, and that time depends on the product, temperature and joint depth.
Sanitary joints that fail early become defects soon after occupation. Water gets behind trays, vanity tops and panels, and the repair falls into the defects period. Proper preparation, with the right silicone first time, keeps it off the defects list.
Diagnose, treat, sign off
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area.

Doing it in-house
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Redoing a failed joint normally 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.

Sites and facades in and around Charter Alley
Central London is about 47 miles from Charter Alley. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. Rainfall across the South East, Charter Alley included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.
For contractors at a school such as The Priory Primary School, sealing has to be finished before term starts. For contractors refurbishing units at places like Berry Court Business Park, 1.7 miles north-east of Charter Alley, the mastic covers cladding panels, roller-door and window perimeters. With historic properties like The Vyne (to the east of Charter Alley) in the area, refurbishment work often meets old masonry that needs compatible sealants.
Charter Alley is about 3 miles south of Tadley, in Hampshire. We send applicators to Charter Alley for mastic packages, handled exactly as we handle every other area. Charter Alley is one of 723 places in Hampshire on our list. Our Reading page has more on work in that area.

Questions about Charter Alley
Can you take on a job at a hospital such as Parklands Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Will you take on work at estates like Berry Court Business Park, close to Charter Alley?
Yes. Our area takes in Charter Alley and its surroundings, with estates and business parks such as Berry Court Business Park included. A few photos and the unit address let us price the work.
How do you work with the site programme?
Working to your programme, we seal each area as it’s handed over. The sequence is agreed with the site manager at the start and updated as the programme moves.
Can staff carry on working while you’re here?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Can you clear a mastic snag list before handover?
Yes. We clear snags by redoing joints rather than patching them, working to your handover date.
Honest limits
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Frames fitted out of tolerance
- Joint design decisions that belong to the architect or engineer
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
If in doubt, call the office on 01277 525 020 or email the details over and we’ll say what we think before you book.
