Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Looking after the joints
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Allow flexibility for external sealing in damp or cold weather
- Get the mastic subcontractor involved early in the programme
- Release areas for mastic once other trades have finished in them
- Check frame gaps are within the sealant’s range before sealing
Brief the sparkle clean so they don’t scrape the new joints. Blades and abrasive pads are the commonest cause of damage at the final clean.
Leaving the mastic snag list to the end squeezes everyone. A planned close-out through each area as it completes keeps the list short and keeps handover on track.
Construction mastic in Alciston
Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone. After that, the joints are prepared and sealed to the specification. Site teams most often ask us about mastic snags holding up handover and frame gaps too wide for sealant alone, on internal decorators’ caulk, floor and skirting junctions and brick and block movement joints. For commercial sealant work in Alciston, you deal with one contact from quote to sign-off, whether it’s one building or several.
Construction in and around smaller places such as Alciston is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

How the job changes by surface
Snagging before handover
The last pass before handover is where mastic snags are cleared. Snags are cleared room by room, cutting out damaged joints and resealing them properly.
Kitchens and utility areas
Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. The sealant is a kitchen-grade product.

What sets the cost
Your fixed quote is built from the real scope. It allows for:
- Removal of failed or old sealant
- The site’s rules and procedures
- The product specified
- Whether the work must be split into stages
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 you will have a fixed figure to work with.
Before you send an enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- Drawings or a marked-up plan, if available
- How the joints are reached, and at what height
- A wide shot and a close-up of the area
- Asbestos survey details if the building is older
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, phone 01277 525 020 or send photos by email.
What we are called out for in Alciston
A joint without backing rod or bond-breaker often fails early. Fixed to three faces, the sealant rips the first time the joint opens so we set the depth properly before sealing.
What tends to prompt an enquiry:
- Internal caulk splitting as the building dries out
- Sealant knocked or painted over by other trades
- Inconsistent sealant finishes from plot to plot
- Window and door perimeters that won’t pass inspection
With historic properties like Charleston Farmhouse (to the north-west of Alciston) in the area, refurbishment work often meets old masonry that needs compatible sealants.
What your quote should include
- Are they CHAS accredited or on Constructionline?
- Do they follow the manufacturer’s priming guidance?
- The named product and why it was chosen
- Can the work be phased to keep areas open?
Why it’s worth doing now in Alciston
Patching snags as they appear can feel quicker than a proper close-out. A planned sweep of each plot or floor catches the lot in one go. We can run snagging as its own phase before handover. Around Alciston, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we’ll quote for the lot.
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.
Why appoint us
- Over 20 years of commercial sealing
- A range of standard colours, depending on the product
- Constructionline member for supplier checks
- Colour options checked against the specified product

For a contractor working at a hospital such as Chailey Heritage Marine Hospital, which lies south-west of Alciston, perimeter and facade sealing is planned around patients and deliveries. Building work at universities like University of Brighton (to the south-west of Alciston) is often timed for the summer, mastic included.

Alciston: questions and answers
Is hospital work, at somewhere like Chailey Heritage Marine Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can work at a site such as University of Brighton fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
What do you charge?
It depends on the job: quantities, access, the product and any phasing. Call for a quote.
Can you quote from photos?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.
Our process
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. For work around Alciston, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised straight away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
What we need from you
- Tell us your opening times and when work is allowed
- Tell us which areas need to stay in use
- Arrange parking or a loading space
