About our mastic sealing in Chipperfield
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. We work on external wall and movement joints, balcony and threshold joints and communal kitchens and washrooms, and what we are called in for most is occupiers reporting cold air round windows and open joints in brickwork or panels. One point of contact handles commercial sealant work in Chipperfield from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Around smaller places like Chipperfield, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why deal with it now?
Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. Halls, stores and units around places like Chipperfield may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

Commercial clients in Chipperfield
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
How the quote is worked out
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- The size and state of each joint
- Travel to remote or island sites
- How much existing material needs removing
- How much there is to seal
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
A few photos plus some basic facts will normally do. Please tell us:
- Any dates the work must fit around
- Photos of the joints, close up and from further back
- The postcode of the building
- Whether an asbestos survey exists

When to bring in a specialist
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so it can be arranged.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Planned mastic for Chipperfield portfolios
Chipperfield sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. Central London is about 22 miles from Chipperfield. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate.
Older buildings near Chipperfield, from historic houses such as Chenies Manor House, 2.9 miles to the south-west of Chipperfield, to more modest stock, need compatible products when frames are resealed. Buildings close to stations like Apsley station, 2.1 miles to the north-east of Chipperfield, are often flats over shops, with frame mastic to keep sound.

What we are called out for in Chipperfield
Communal entrances and corridors see a lot of wear, and low-level joints get damaged. Cleaning products add to the wear.
These are often picked up first by site or facilities staff:
- Occupiers reporting cold air round windows
- Water getting in round frames after rain
- Failed external movement joints
- Repeated reactive repairs to the same buildings
Trustees of buildings like Church of St Paul can bring frame and external mastic into a planned maintenance list.
