Construction mastic in Chartwell Green, done properly
Getting a subcontractor through site induction should be simple. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. We work on window and door perimeters, floor and skirting junctions and cladding and panel joints, and what we are called in for most is different trades sealing to different standards and perimeter gaps outside the sealant’s range. Whether you call it commercial sealant work, mastic application or joint sealing, in Chartwell Green it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around places like Chartwell Green, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What happens if it’s left?
On a refurbishment, there’s a choice between resealing existing frames and replacing them. If the frame is in good order, cutting out and resealing the perimeter can be all it needs. We will say so if a frame itself is the problem. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

What else we do in Chartwell Green
General trades versus a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
For most general trades, sealant is a sideline. 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.
Construction mastic around Chartwell Green: how the place shapes the job
Rainfall across the South East, Chartwell Green 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. The area within 2 miles of Chartwell Green holds several hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
Recladding or extending a unit at a site like Seddul Bahr Industrial Estate, 1.4 miles north-east of Chartwell Green, brings panel joints and frame perimeters into the programme. When a college such as Itchen College (1.5 miles south of Chartwell Green) builds or refurbishes, the mastic package normally has to fit around students and staff. Hotels like Bitterne Park Hotel, 1.2 miles to the west of Chartwell Green, rarely close for long, so refurbishment mastic is phased floor by floor.
Chartwell Green is about 2 miles north-east of Southampton, in Hampshire. Businesses, contractors and managing agents in Chartwell Green can call on us for mastic packages. Chartwell Green is one of 723 places we cover in Hampshire.

What the job involves on each surface
Internal decorators’ caulk
Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s paintable and suits gaps that don’t move, and we use a flexible sealant where there’s movement.
Window and door perimeters
A frame gap that’s too wide can’t just be filled with sealant. Gaps outside the product’s range are raised with the site team.
FAQs: Chartwell Green
Does your area include sites such as Seddul Bahr Industrial Estate, near Chartwell Green?
Yes. Estates, retail parks and business parks around Chartwell Green, Seddul Bahr Industrial Estate among them, are all within reach. To start, just phone 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Would you work within a site like Moorgreen Hospital?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What hours do you work?
We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
From enquiry to sign-off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses.

Honest limits
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Approving fire stopping as compliant
- Designing joint widths or choosing the specification (that sits with the designer)
- Glazing units that are cracked or misted
Not sure which it is? You can call 01277 525 020 or email us and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Floor and skirting junctions
- Brick and block movement joints
- Cladding and panel joints
- Window and door perimeters
- Sanitary and kitchen joints
- Internal decorators’ caulk
Looking after the joints
To get the most from the new sealant:
- Keep product details for future maintenance
- Share drawings and the specification as soon as possible
- Bring the mastic contractor in after the last trades are through
- Ask cleaners to use soft cloths around fresh sealant
Record which products went where in the handover file. Future maintenance is easier when the products are known and avoids guesswork when joints are renewed. Tell us what records you need and we’ll confirm with the quote.
Leaving the mastic snag list to the end squeezes everyone. Clearing snags area by area spreads the work out.
