Cost factors for mastic joints
A fixed quote reflects the actual work. It takes account of:
- How accessible the joints are
- Whether old sealant has to be cut out first
- Phasing around occupants
- Which sealant the job calls for
A quote for mastic joints depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.
Details that help us quote
Whether it’s one area or a whole building, these details speed things up:
- How the joints are reached, and at what height
- Whether the building will be occupied during the work
- Any specification or named product
- The asbestos register, for older buildings
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Mastic sealing in Bitchet Green
We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed, with backing rod setting the depth where it’s needed. We work on external wall and movement joints, window and door perimeters on blocks and shopfronts below residential blocks, and the failures we’re asked to look at most are patchy repairs in mismatched sealant and leaks at window and door perimeters. For commercial sealant work in Bitchet Green, you deal with one contact from quote to sign-off, whether it’s one building or several.
Owners and agents with buildings around smaller places such as Bitchet Green tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, ring 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

Central London is about 22 miles from Bitchet Green. Managed blocks of flats are a big part of commuter-belt property. Bitchet 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.

Schools and community buildings such as St Lawrence Church of England Primary School need frame and external mastic kept sound like any building.

Do you need mastic sealing in Bitchet Green?
Much failed sealant was laid on dirty, dusty or damp surfaces. Without clean, sound faces and a primer where the product needs one, the bead peels off one side.
If one of these sounds familiar, it’s time for a closer look:
- The same joint failures repeated across a portfolio
- Complaints coming in block by block
- Movement joints with sealant missing
- Cracked, hardened mastic round windows on a block
Older buildings near Bitchet Green, from historic houses such as Ightham Mote (1 mile south-east of Bitchet Green) to more modest stock, need compatible products when frames are resealed.
Questions to ask before you book
- Will RAMS and insurance details be available?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How the existing material will be dealt with
- Who will actually carry out the work
Commercial clients in Bitchet Green
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.
CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.
Our process
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Jobs in and around smaller places like Bitchet Green are usually planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- We check the asbestos register for older buildings and look at the joints.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
Preparing the site
- Arrange parking or a loading space
- Confirm the product named in the specification
- Share the asbestos register for older buildings

Every quote starts with the facts: 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.

Bitchet Green: questions and answers
Does your area include sites such as Chaucer Business Park, near Bitchet Green?
Yes. Estates, retail parks and business parks around Bitchet Green, Chaucer Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Will you take on a block within reach of Kemsing station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Can you plan resealing across several buildings?
We can. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it.
How do you reach windows on upper floors?
It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.
Will residents or tenants be disturbed?
The work is planned around occupiers. We agree the programme so you can notify occupiers, and entrances stay in use.

How the job changes by surface
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.
Honest limits
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Water coming in from the roof or rainwater goods
- Leaks through the frame itself rather than the perimeter
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If you are not sure, just call the office on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.
