Doing it in-house
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
How we handle construction mastic in Blean
Perimeter sealing outside needs a dry joint and the right temperature. Cold or damp mornings, frost and condensation on frames can all hold external sealing up. Internal sealing often fills those days. We work on brick and block movement joints, window and door perimeters and floor and skirting junctions, and the usual reasons a site gets in touch are a mastic package split between trades with no clear owner and new external sealant already peeling away. One point of contact handles commercial sealant work in Blean from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Construction in and around smaller places such as Blean is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Questions about Blean
Can you take on a job at a hospital such as Eastbridge Hospital of St Thomas the Martyr?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you cover business parks and estates near Blean, such as John Roberts Business Park?
Yes. We cover Blean and the area around it, including industrial estates, business parks and retail parks such as John Roberts Business Park. Photos and a short description are enough for a first look.
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 do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Does weather affect external mastic work?
External sealing goes ahead only with a dry joint inside the product’s temperature range. Sealing in poor conditions risks adhesion failure so it’s better to wait.
Can you work to our specification?
Specification first, then the maker’s instructions. Primers, backing and joint depth follow what the manufacturer sets out.
From enquiry to sign-off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. Jobs in and around smaller places like Blean are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- First we take quantities off the drawings and read through the specification.
- We return a fixed quote that ties the mastic package to your programme.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- We close out snagging and hand over with a 12-month guarantee.
Getting the site ready
- Point out any areas we must not close
- Send any specification or drawings in advance
- Share your working hours and any access restrictions
Ask for a quote
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
Advice
Signs you need construction mastic in Blean
Value-engineered products sometimes end up in the wrong joints. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We use what’s specified, and any substitute goes to you for acceptance.
Most enquiries start with one or more of the following:
- Snag items on joints that need redoing before handover
- External joints sealed in damp or cold conditions that are now failing
- Sanitary sealant damaged by following trades
- Old sealant on a refurbishment that needs stripping before new work
For contractors at a school such as Blean Primary School, sealing has to be finished before term starts.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- Are they CHAS accredited or on Constructionline?
- Whether old or failed sealant will be cut out, not overlaid
- Their public liability cover
When something else is needed
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Joints damaged after sign-off by following trades
- Approving fire stopping as compliant
If in doubt, ring 01277 525 020 or email drawings and photos and we’ll say what we think.
What we seal
- Floor and skirting junctions
- Brick and block movement joints

Facades, frames and programmes in Blean
Rainfall across the South East, Blean included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team. Blean is about 51 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes.
Units on estates such as John Roberts Business Park (to the north-west of Blean) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. On a campus such as University of Kent, 1.2 miles to the south-east of Blean, new teaching buildings and residences are usually built and refurbished around the academic year.
Blean is about 3 miles north-west of Canterbury, in Kent. We cover Blean and the rest of Kent, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Kent, 931 places are covered, Blean among them. There’s a separate page for London, roughly 51 miles from Blean.

Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- Ask cleaners to use soft cloths around fresh sealant
- Ask installers to correct oversized gaps first
- Ask for joint and product checks before the package is urgent
- Don’t schedule sealing before decorators and flooring are done
Any damage after we’ve finished should go on the snag list straight away. Snags can be picked up in a planned close-out visit, priced as part of the package or separately.
A missed perimeter seal on one window can wet the reveal and the plaster inside. On a new building that means remedial work after decorating. Checking perimeters before internal finishes go on avoids it.
