Common questions from Chartwell Green clients
Does your area include sites such as Seddul Bahr Industrial Estate, near Chartwell Green?
Yes. We cover Chartwell Green and the area around it, including industrial estates, business parks and retail parks such as Seddul Bahr Industrial Estate. Photos and a short description are enough for a first look.
Can work in a care setting near Chartwell Green go ahead while residents are there?
Yes. We work around residents’ routines, a room or two at a time. Any site rules, from signing in to infection control, are agreed before we start.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Can you seal joints high up on a block?
It depends on the building. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
Do you need to see the site first?
It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs usually get a visit.
Do you work with property factors and landlords?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order so you can plan around it.
About our mastic sealing in Chartwell Green

Each building we complete carries a 12-month guarantee on our workmanship. If you’re dealing with failed external movement joints and brittle perimeter mastic across a building, we can help.

Converted and older buildings in and around Chartwell Green often put modern windows into old walls. The mastic there needs to suit both surfaces.

What else we do in Chartwell Green
Looking after buildings in and around Chartwell Green
Chartwell Green sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first. Chartwell Green has five care or nursing homes no more than 2 miles away. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents.
Student accommodation around universities such as University of Southampton, 2.2 miles to the west of Chartwell Green, is typically managed block by block, which suits a planned mastic programme. Schools and community buildings such as Townhill Infant School need frame and external mastic kept sound like any building.

When to call us in Chartwell Green
Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone and the repair soon fails.
Most enquiries start with one or more of the following:
- Draughts at frames across a block
- Movement joints with sealant missing
- Mastic failing across several blocks on an estate
- A mix of products and colours from past repairs
Older community buildings, Church of St James among them, often have frames of mixed ages whose mastic varies.
What your quote should include
- Whether old or failed sealant will be cut out, not overlaid
- How long is the guarantee, and what does it include?
- Proof of insurance
- Health and safety accreditation such as CHAS
Why it’s worth doing now in Chartwell Green
Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

For managing agents and facilities managers
Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
What sealant work can’t fix
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Asbestos-containing sealant, which we don’t remove
- Failed window or door frames, which need a window contractor
- Roof leaks, gutters or failed flashings that aren’t sealant joints
If you’re not sure, just call 01277 525 020 or use the quote form and we will give you a straight answer.
Joints and surfaces we work on
- Window and door perimeters on blocks
- Balcony and threshold joints
- Shopfronts below residential blocks
- Communal kitchens and washrooms
- External wall and movement joints
- Communal entrances and stairwells
Site staff or a sealant specialist?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
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. A poor seal in places like these tends to cost more to put right later.
