Facades, frames and programmes in Shalcombe
Shalcombe sits close to the coast, within about 2 miles. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. Rainfall across the South East, Shalcombe 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 external mastic is timed for workable conditions and agreed with the site manager.
With historic properties like Mottistone Manor, 1.3 miles south-east of Shalcombe, in the area, refurbishment work often meets old masonry that needs compatible sealants.
Shalcombe is about 6 miles west of Newport, in the Isle of Wight. Any commercial site in Shalcombe is covered, for single jobs and planned programmes alike. Shalcombe is one of 125 places we cover in the Isle of Wight for mastic packages. We also cover Southampton, some 17 miles away.

What sealant work can’t fix
Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:
- Damage to finishes by other trades after we have sealed
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Defective windows, doors or glazing units (the supplier or installer’s job)
If you’re not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer before you book.
What we seal
- Brick and block movement joints
- Window and door perimeters
- Floor and skirting junctions
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Cladding and panel joints
Why it’s worth doing now in Shalcombe
A cheaper sealant can look like an easy saving on a large package. The saving is small next to the cost of callbacks and defects, especially externally. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Converted and older buildings near places like Shalcombe tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Your questions answered
Does the sea air around Shalcombe change the choice of sealant?
It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.
Is Shalcombe off your patch?
Not at all. Shalcombe is within our area. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Do your applicators hold CSCS cards?
We’re CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. We confirm any paperwork you need with the quote.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Does weather affect external mastic work?
External sealant needs a dry joint and a temperature within the product’s range. Damp, frost or condensation on frames can stop work, so internal areas are often done on those days.
What will the job cost?
There isn’t a price list, because every site is different. With photographs or drawings, we can give you a fixed quote.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Advice
What we’re called out for in Shalcombe
On construction sites, joints usually fail early because of when they were sealed, not what was used. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage, so they end up back on the snag list.
It’s worth sending us details if you spot any of the following:
- Old sealant on a refurbishment that needs stripping before new work
- External joints sealed in damp or cold conditions that are now failing
- Missed perimeter joints on a new elevation
- Sanitary sealant damaged by following trades
On any site in or around Shalcombe, the mastic follows the specification and the programme.
Before you book anyone
- Their pre-qualification and accreditations
- Which product they’ll use, and why it suits the joint
- What site paperwork they can supply
- Their approach to joint depth and backing
Aftercare for building managers
Once the work is signed off, a little attention goes a long way:
- Don’t schedule sealing before decorators and flooring are done
- Note which sealant went where at handover
- Brief the final clean team to avoid blades near sealant
- Allow flexibility for external sealing in damp or cold weather
Brief the sparkle clean so they don’t scrape the new joints. Scrapers used on frames and worktops can nick or lift a new bead.
Sanitary joints that fail early become defects soon after occupation. Leaks behind showers and basins damage finishes and floors, and the repair falls into the defects period. Proper preparation, with the right silicone first time, keeps it off the defects list.
