How we handle mastic sealing in Preston Candover
Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Entrances and stairwells are kept in use while we work. Site teams most often ask us about window mastic that has split and shrunk and complaints coming in block by block, on external wall and movement joints, balcony and threshold joints and communal entrances and stairwells. A single leaking joint is often how a building in Preston Candover first comes to us: we look at the rest while we’re there and tell you what we find.
Rural conversions near places like Preston Candover often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Keeping the joints sound
Your facilities or cleaning team can help the joints last. Share these points with them:
- Group repairs into a planned programme
- Share your contractor requirements early
- Start inspections with the most exposed faces
- Log resealing dates block by block
Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.
Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings so spending is spread.
Different surfaces, different methods
Tenement and older buildings
Stone needs a neutral-cure product, so we pick a grade that won’t mark it.
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
What affects the price in Preston Candover
The price varies from site to site. Expect it to depend on:
- The site’s rules and procedures
- Specialist products, such as fire-rated or hygienic sealants
- Any access equipment needed
- How much there is to seal
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Details that help us quote
Good information means a firmer quote. When you get in touch, include:
- Whether an asbestos survey exists
- Photos of the joints, close up and from further back
- The type of building and who uses it
- The postcode of the building
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.
From enquiry to sign-off
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Smaller jobs around Preston Candover can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Can you quote for mastic across several buildings in and around Preston Candover?
Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.
Do you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Can you take on resealing for a block portfolio?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order so you can plan around it.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Is mastic sealing guaranteed?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Common problems we fix in Preston Candover
Much failed sealant was laid on dirty, dusty or damp surfaces. Without clean, sound faces and a primer where the product needs one it comes away from one face.
Most enquiries start with one or more of the following:
- The same joint failures repeated across a portfolio
- Open joints in brickwork or panels
- Damp patches beside frames
- Repeated reactive repairs to the same buildings
For owners of several units at places like Barton Industrial Estate (2.6 miles south-east of Preston Candover), one programme can deal with frame and external mastic across the lot.
Questions to ask before you book
