Signs you need mastic sealing in Highcliffe
UV and rain age external sealant. It stiffens, stops stretching and cracks, especially on south and west faces.
Things that typically lead to an enquiry:
- Failed external movement joints
- Estate-wide sealant that is simply worn out
- Cracked, hardened mastic round windows on a block
- Complaints coming in block by block
For agents with blocks near Winchester station, which lies north-west of Highcliffe, a block-wide mastic programme deals with frames, balconies and entrances in one go.
What your quote should include
- Will failed sealant be removed rather than covered?
- Are they CHAS accredited or on Constructionline?
- What level of public liability insurance do they hold?
- Do they follow the manufacturer’s priming guidance?
Mastic sealing in Highcliffe, done properly
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 and we quote and schedule each building in turn. If you have damaged joints in communal entrances and corridors and cracked, hardened mastic round windows on a block, we can help, whatever the surface. Facilities teams, main contractors and managing agents in Highcliffe tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Places the size of Highcliffe typically have some housing association stock, small blocks and mixed-use buildings. The mastic around their frames and external joints ages like anywhere else.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Leaks through the frame itself rather than the perimeter
Not sure which it is? You can phone 01277 525 020 or email the details over and we will tell you honestly.
Joints and surfaces we work on
- Shopfronts below residential blocks
- External wall and movement joints
- Communal entrances and stairwells
- Balcony and threshold joints
- Communal kitchens and washrooms
- Window and door perimeters on blocks
Our process
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. What matters most for a job in Highcliffe is a clear list of what needs doing, so send photos of each area. You will then get a fixed price for the work.
- Each block or building is walked and the failed joints recorded with the likely cause.
- You get a fixed quote, priced per building where that helps your budgeting.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Before we start on site
- Flag any permit to work we will need
- Arrange parking or a loading space
- Confirm the product named in the specification

Questions about Highcliffe
Will you work in a care home in Highcliffe without moving residents out?
Yes. We work around residents’ routines, a room or two at a time. Any site rules, from signing in to infection control, are agreed before we start.
Is Highcliffe too far out for you?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
How do you reach windows on upper floors?
It depends on the building. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
How long does a job like this take?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
How the quote is worked out
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- The product specified
- Induction, permit and paperwork requirements
- How accessible the joints are
- Quantities, in metres or numbers
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
Details that help us quote
Diagnosis starts before we arrive. Tell us:
- Whether an asbestos survey exists
- What the building is and how it’s used
- How the joints are reached, and at what height
- Photos of the joints, close up and from further back
