How we handle mastic sealing in Waterbeach
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. We work on communal entrances and stairwells, window and door perimeters on blocks and balcony and threshold joints, and the failures we are asked to look at most are occupiers reporting cold air round windows and patchy repairs in mismatched sealant. Whoever orders the work in Waterbeach, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For buildings around smaller places like Waterbeach, we group work so one trip covers it. Send photos of the frames and joints and we’ll give a fixed quote.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Block-wide mastic in Waterbeach
There are two care or nursing homes within about 2 miles of Waterbeach. Care home owners need frame and external mastic kept sound without unsettling residents. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building typically need attention first.
Older community buildings, The Priory Church of St Mary and St Blaize among them, often have frames of mixed ages whose mastic varies. Site managers at schools like Boxgrove CofE Primary School can fit frame mastic into the summer works.
Waterbeach is about 3 miles north-east of Chichester, in West Sussex. We send applicators to Waterbeach for mastic joints, handled exactly as we handle every other area. Waterbeach is one of 373 places we cover in West Sussex for mastic joints. Our Portsmouth page has more on work in that area, about 16 miles away.

Why it’s worth doing now in Waterbeach
Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go and is simpler to manage and budget. Older rural buildings around Waterbeach move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

What sealant work can’t fix
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Leaks from above rather than through a joint
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Leaks through the frame itself rather than the perimeter

Owners, agents and contractors
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.
How a job runs
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. For a building around Waterbeach, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Getting the site ready
- Send asbestos survey details if the building is pre-2000
- Send your site hours and access windows
- Explain the parking and delivery arrangements

Do you supply RAMS and insurance details?

What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
Can you seal joints high up on a block?
Every block is different. How upper joints are reached is agreed before work is booked so there are no surprises.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
What we’re called out for in Waterbeach
Previous repairs often sealed new mastic over old. New sealant won’t grip failed sealant and the repair soon fails.
These are often picked up first by site or facilities staff:
- Window mastic that has split and shrunk
- Patchy repairs in mismatched sealant
- Damaged joints in communal entrances and corridors
- Complaints coming in block by block
Student accommodation around universities such as University of Chichester (2.3 miles south-west of Waterbeach) is normally managed block by block, which suits a planned mastic programme.
What to look for in a quote
- How they’ll work around occupants
- Whether old or failed sealant will be cut out, not overlaid
- What level of public liability insurance do they hold?
- Do they follow the manufacturer’s priming guidance?
Looking after the joints
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Log resealing dates block by block
- Prioritise elevations facing the weather
- List the paperwork your organisation requires when you send details
- Avoid piecemeal callouts where you can
If a joint we sealed fails within 12 months, tell us and we’ll look at it. Beyond that, routine checks spot the next round of repairs.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order and work down the list.
