Mastic sealing for Gestingthorpe sites

How we handle mastic sealing in Gestingthorpe
In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. Site teams most often ask us about brittle perimeter mastic across a building and patchy repairs in mismatched sealant, on communal entrances and stairwells, balcony and threshold joints and shopfronts below residential blocks. A specialist sealant contractor works differently from a general builder: in Gestingthorpe, that means joint design, primers and backing rod as standard.
For buildings around smaller places like Gestingthorpe, we group work so one trip covers it. Send photos of the frames and joints and we’ll give a fixed quote.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- Water coming in from the roof or rainwater goods
- Leaks through the frame itself rather than the perimeter
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If in doubt, speak to us on 01277 525 020 or send photos by email and we’ll say what we think before you book.

Questions about Gestingthorpe
We manage a building near Sudbury (Suffolk) station. Can you help?
Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Is Gestingthorpe too far out for you?
No. Places such as Gestingthorpe are covered as much as the big towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn with dates agreed in advance.
Can you reseal a whole block or estate?
Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
Is mastic sealing guaranteed?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
Commercial clients in Gestingthorpe
For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first.
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.
Why deal with it now?
Leaving failed external joints lets water reach the structure behind. Damp patches, stained plaster and decorating claims can follow and those cost far more to put right. Halls, stores and units around places like Gestingthorpe may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
