Rural conversions near places like Brantham often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Why it’s worth doing now in Brantham
Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish and one 12-month guarantee. Older rural buildings around Brantham move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

FAQs: Brantham
Is Brantham off your patch?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Will you take on a block within reach of Manningtree station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Can you reseal a whole block or estate?
Yes. We survey and price each building, then work through them in order starting wherever is most urgent.
What guarantee do you give on resealing?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
Can you send RAMS and CSCS details before starting?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Before you send an enquiry
Whether it’s one area or a whole building, the same details help:
- Where the site is, with the postcode
- Access details, including height
- Clear photographs of the problem areas
- The product your specification calls for
To get a fixed quote, phone 01277 525 020 or send photos by email with the site address and an outline of the work. Our quote form is another easy route.
Aftercare for building managers
To get the most from the new sealant:
- Look at the sunniest and most exposed elevations first
- Plan resealing building by building rather than complaint by complaint
- Track which buildings were done and when
- List the paperwork your organisation requires when you send details
Log the date and extent of the resealing for each block. It helps plan the next round and gives you a history.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and saves internal repairs.
