Mastic sealing in Bernards Heath
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
General trades versus a specialist
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. For that reason, many FMs and contractors use a sealant specialist from the outset.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Mastic sealing for commercial buildings in Bernards Heath
Managing agents and housing associations usually need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. If you’re dealing with damp patches beside frames and cracked, hardened mastic round windows on a block, we can help, on communal kitchens and washrooms, window and door perimeters on blocks and external wall and movement joints alike. Facilities teams, main contractors and managing agents in Bernards Heath tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In a smaller place such as Bernards Heath, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. The mastic around their frames and external joints ages like anywhere else.
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.

Maintenance after handover
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Keep a record of when each building was resealed
- Check the asbestos register before any old mastic is disturbed
- Check sealant joints during planned building inspections
- Encourage occupiers to report problems at frames
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order and work down the list.
Do you need mastic sealing in Bernards Heath?
The edges of the material itself sometimes break away for instance where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.
Things that normally lead to an enquiry:
- Mastic failing across several blocks on an estate
- Draughts at frames across a block
- Window mastic that has split and shrunk
- Damp patches beside frames
If you’re responsible for a building such as Church of St Saviour, frame and door mastic needs the same attention as any other property.
Questions to ask before you book
- Are they CHAS accredited or on Constructionline?
- The named product and why it was chosen
- Will failed sealant be removed rather than covered?
- How joint depth will be controlled

How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- Any access equipment needed
- Whether old sealant has to be cut out first
- How much there is to seal
- Induction, permit and paperwork requirements
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.
What we need to price the job
A few photographs plus some basic facts will normally do. Please tell us:
- Asbestos survey details if the building is older
- Specification clauses that apply
- When you need the work done
- Clear photos of the problem areas
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
Your questions answered
Can you work in a care home near Bernards Heath with residents in?
Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.
Can you work at a site such as Sandridge Gate Business Centre, by Bernards Heath?
Yes. Our area takes in Bernards Heath and its surroundings, with estates and business parks such as Sandridge Gate Business Centre included. To start, just call 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Do you work with property factors and landlords?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.
Will you come and look before quoting?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
