Mastic sealing for commercial buildings in The Valley
There isn’t one mastic for every joint on a building. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. If you are dealing with water getting in round frames after rain and patchy repairs in mismatched sealant, we can help, on communal entrances and stairwells, balcony and threshold joints and window and door perimeters on blocks alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in The Valley is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places like The Valley, 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.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Signs you need mastic sealing in The Valley
Previous repairs often sealed new mastic over old. New sealant won’t grip failed sealant and the repair soon fails.
Typical triggers for a call:
- Window mastic that has split and shrunk
- Movement joints with sealant missing
- Water getting in round frames after rain
- Repeated reactive repairs to the same buildings
Blocks of flats and mixed-use buildings often cluster around stations such as Charing station (3.2 miles south of The Valley) and their window and balcony mastic tends to age at the same rate across a building.
What your quote should include
- Can the work be phased to keep areas open?
- Their public liability cover
- What site paperwork they can supply
- Their approach to joint depth and backing

Building owners, agents and FMs in The Valley
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.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Keeping the joints sound
A few simple habits keep the new joints working:
- Share your contractor requirements early
- Log resealing dates block by block
- Share the asbestos register when you send details
- Prioritise elevations facing the weather
Add mastic joints to your cyclical inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.
Mastic sealing in The Valley: the local picture
Central London is about 42 miles from The Valley. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building normally need attention first.
Older community buildings, Church of St Lawrence among them, often have frames of mixed ages whose mastic varies. Historic properties like Belmont House and Gardens (to the north-east of The Valley) show the age of some local stock, where frame mastic must suit soft brick or stone.
The Valley is about 6 miles south-west of Faversham, in Kent. Across the ME13 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 931 places in Kent. We also cover London, around 42 miles from The Valley.

Quoting for work in The Valley
Your fixed quote is built from the real scope. It takes account of:
- Whether old sealant has to be cut out first
- Access and working height
- Joint width, depth and condition
- Whether the work must be split into stages
Access can matter as much as the joints themselves: 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.
What to include in your enquiry
For an accurate fixed quote, we need to understand the site. Useful things to include:
- The site address and postcode
- Anything awkward about access or site hours
- Specification clauses that apply
- Whether an asbestos survey exists
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.
Questions about The Valley
Is The Valley too small for you to travel to?
No. Places such as The Valley are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Do you work for managing agents with blocks near Charing station?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
Can you send RAMS and CSCS details before starting?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.
What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
How do you handle work on occupied blocks?
We plan around people living or working in the building. We agree the programme so you can notify occupiers and communal access is kept open.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the building height and any access already in place, and we will tell you how we’d approach it.
Why it’s worth doing now in The Valley
Draughts round window perimeters cost occupiers comfort, and they often blame the windows. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Older rural buildings around The Valley move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

- Workmanship guaranteed for 12 months
