Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Our process
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Smaller jobs around Dallington can be grouped with others nearby. A fixed quote is given before anything starts.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.

How we handle mastic sealing in Dallington
Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Entrances and stairwells are kept in use throughout. Site teams most often ask us about cracked, hardened mastic round windows on a block and occupiers reporting cold air round windows, on communal entrances and stairwells, window and door perimeters on blocks and communal kitchens and washrooms. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Dallington is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In and around smaller places like Dallington, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When it isn’t the sealant
We check first that sealant really is the fix. It won’t put right:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Frames that are rotten, warped or broken
- Broken glass or failed sealed units
If in doubt, ring 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.
Surfaces we seal
- Communal kitchens and washrooms

- Balcony and threshold joints
- External wall and movement joints
What the job involves on each surface
Commercial and mixed-use buildings
Landlords with commercial portfolios have shopfronts, office entrances and external joints to look after. A planned programme suits multi-building portfolios.
Window and door perimeters on blocks
Frames vary from uPVC to aluminium and timber, so the grade we pick has to bond to frame and wall alike. Colours are confirmed for the product used.
Looking after buildings in and around Dallington
Dallington sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. Dallington is about 43 miles from central London. Within reach of London, blocks run by agents and associations are common around stations.
If you’re responsible for a building such as The Parish Church of St Giles, frame and door mastic needs the same attention as any other property. For a school such as Dallington Church of England Primary School, perimeter mastic on windows and doors is a holiday job. With historic buildings such as Bateman's, 3.1 miles north of Dallington, in the wider area, owners of older properties around Dallington should expect mastic to need a product that suits old masonry.

Why act early in Dallington
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once, under a single quote and a single programme. Around Dallington, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we’ll quote for the lot.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Questions about Dallington
Can you quote for mastic across several buildings in and around Dallington?
Yes, we quote for single buildings and for programmes across several blocks. Send the addresses and photos and we will give a fixed quote.
What site paperwork comes with a job in Dallington?
We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.
Is asbestos a concern with old mastic?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
Will residents or tenants be disturbed?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.
Which sealant will you use?
The specification comes first, if there is one. 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.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Commercial clients in Dallington
CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Doing it in-house
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
