Mastic sealing in Dedham
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. If you have a mix of products and colours from past repairs and open joints in brickwork or panels, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Dedham it comes down to the same thing: the right product in a properly prepared joint.
Around smaller places like Dedham, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

FAQs: Dedham
Does your area include sites such as Blue Barns Business Park, near Dedham?
Yes, sites like Blue Barns Business Park are within our area, along with the rest of Dedham. Send details of the unit and the work through our quote form for a quick quote.
Is Dedham off your patch?
No. Places such as Dedham are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit usually takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we’ll set out a timescale with the quote.
How do you handle work on occupied blocks?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

What sets the cost
Your fixed quote is built from the real scope. It takes account of:
- Backing rod, priming and other preparation
- Travel to remote or island sites
- Quantities, in metres or numbers
- Induction, permit and paperwork requirements
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.
What we need to price the job
Diagnosis starts before we arrive. Tell us:
- Approximate linear metres or a joint schedule
- Whether an asbestos survey exists
- The site address and postcode
- Any specification or named product
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email a schedule or drawings.
What the job involves on each surface
Window and door perimeters on blocks
Frames vary from uPVC to aluminium and timber, so the grade we pick has to bond to frame and wall alike. We will confirm the colours available for the specified product.

Priority order can follow condition, complaints or your maintenance plan. You get one fixed quote per building or for the whole estate.

Why act early in Dedham
A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. One visit to deal with every failing joint makes more sense than several trips to a place like Dedham, rather than one at a time. Photos of every joint help us quote for the whole job.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Looking after the joints
Your facilities or cleaning team can help the joints last. Share these points with them:
- Share your contractor requirements early
- Protect low-level joints in entrances
- Make it easy for occupiers to report draughts
- Avoid piecemeal callouts where you can
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
