Construction mastic in Worthy Down
Mastic follows everyone else, which means it absorbs every delay upstream. The sequence is set with the site team and updated as plots or floors are handed over, so applicators arrive when areas are genuinely ready. That keeps the work right first time and saves rework. We work on sanitary and kitchen joints, floor and skirting junctions and window and door perimeters, and what we are called in for most is failed sealant in an existing building being refurbished and a mastic package split between trades with no clear owner. A single leaking joint is often how a building in Worthy Down first comes to us: we look at the rest while we’re there and tell you what we find.
Around smaller places like Worthy Down, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
We stand by our work with a 12-month guarantee. That covers our preparation and application.

What else we do in Worthy Down
Cost factors for mastic packages
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Which sealant the job calls for
- Backing rod, priming and other preparation
- Phasing around occupants
- How accessible the joints are
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
What we need to price the job
The more we know, the firmer the quote. Helpful details to send:
- Approximate linear metres or a joint schedule
- The type of building and who uses it
- How the joints are reached, and at what height
- Where the site is, with the postcode
Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. If you have questions first, ring 01277 525 020 or email the details over.
Keeping the joints sound
Cleaning and maintenance staff play a part too. Share these points with them:
- Check frame gaps are within the sealant’s range before sealing
- Keep product details for future maintenance
- Stick to the specified sealant rather than a generic substitute
- Keep finished joints away from paint, plaster and scrapers
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.
Snag items left to the last week put handover at risk. Clearing snags area by area spreads the work out and keeps handover on track.
Questions about Worthy Down
Can you take on a job at a hospital such as Royal Hampshire County Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Can you work around term dates at a campus such as University of Winchester?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
How long does a typical visit take?
The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.
Will you stick to the specified products?
Specification first, then the maker’s instructions. Primers, backing and joint depth follow what the manufacturer sets out.
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.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.
What we are called out for in Worthy Down
Wide, tapered or inconsistent gaps around frames are a common problem. Every product has limits on how wide a joint it can bridge and gaps beyond it need packing or adjusting by the frame installer. We flag them early rather than filling them with sealant that won’t last.
Site and facilities staff are often the first to spot these:
- Snag items on joints that need redoing before handover
- Old sealant on a refurbishment that needs stripping before new work
- Frame gaps too wide for sealant alone
- Internal caulk splitting as the building dries out
Projects at schools like South Wonston Primary School work to term dates, so mastic is programmed tightly.
What to look for in a quote
- Proof of insurance
- Are they CHAS accredited or on Constructionline?
- What site paperwork they can supply
- Whether primer will be used where the manufacturer specifies it
When something else is needed
Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:
- Approving fire stopping as compliant
- Oversized gaps that need packing or adjustment by others
- Designing joint widths or choosing the specification (that sits with the designer)
If in doubt, phone 01277 525 020 or send photos by email and we will say what we think before you book.
Surfaces we seal
- Brick and block movement joints
- Internal decorators’ caulk
- Window and door perimeters
- Cladding and panel joints
- Floor and skirting junctions
- Sanitary and kitchen joints

Construction mastic in Worthy Down: the local picture
Rainfall across the South East, Worthy Down included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack. Central London is about 60 miles from Worthy Down. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.

When a college such as Peter Symonds College, 2.6 miles to the south of Worthy Down, builds or refurbishes, the mastic package typically has to fit around students and staff.
