About our mastic sealing in Dymchurch
Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. 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. Site teams most often ask us about no planned programme for sealant and worn sealant at communal door frames, on external wall and movement joints, shopfronts below residential blocks and window and door perimeters on blocks. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Dymchurch, preparation and product choice get the time they need.
Places the size of Dymchurch typically have some housing association stock, small blocks and mixed-use buildings. The mastic around their frames and external joints ages like anywhere else.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Misted or failed double-glazed units
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Asbestos-containing sealant, which we don’t remove
If in doubt, give us a call on 01277 525 020 or send details through our quote form and we will say what we think.
Surfaces we seal
- Shopfronts below residential blocks
- External wall and movement joints

Mastic sealing around Dymchurch: how the place shapes the job
Dymchurch is within about 1 mile of the coast. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints, so it’s worth inspecting those sides more often. Dymchurch is about 57 miles from central London. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide.
If you are responsible for a building such as Church of St Peter and St Paul, frame and door mastic needs the same attention as any other property. Older buildings near Dymchurch, from historic houses such as Westenhanger Castle (4.5 miles north of Dymchurch) to more modest stock, need compatible products when frames are resealed. For a school such as Dymchurch Primary School, perimeter mastic on windows and doors is a holiday job.
Dymchurch is about 4 miles south-west of Hythe, in Kent. Our applicators travel to Dymchurch for work on mastic joints. Dymchurch is one of 931 places in Kent on our list for mastic joints. For work in that direction, see our Brighton page (51 miles or so).

Around Dymchurch
Recent enquiries here include premises near The Ship Inn and the streets around them. The nearest railway station is Westenhanger station, roughly 4.6 miles north of the centre. A little further out are Lympne Castle (2.9 miles north).
General trades versus a specialist
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Dymchurch: questions and answers
Will you take on a block within reach of Westenhanger station?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
Is Dymchurch too small for you to travel to?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Can you take on resealing for a block portfolio?
Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.
How long does a job like this take?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
Do you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Will residents or tenants be disturbed?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
On site: what to expect
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. Several jobs near Dymchurch can be grouped on one trip. Mention the building’s opening times and we’ll work within them.
- Each block or building is walked and the failed joints recorded with the likely cause.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Old sealant is stripped and each face prepared back to firm material.

What happens if it’s left?
Leaving failed external joints lets water reach the structure behind. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
