Need mastic sealing in St Mary's Bay?
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Why deal with it now?
Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go, under a single quote and a single programme. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What you get with us
- Health and safety: CHAS accredited
- Sealing commercial buildings since 2005

About our mastic sealing in St Mary's Bay
Different joints need different sealants. 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. We work on communal kitchens and washrooms, communal entrances and stairwells and shopfronts below residential blocks, and the failures we’re asked to look at most are occupiers reporting cold air round windows and brittle perimeter mastic across a building. A single leaking joint is often how a building in St Mary's Bay first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Converted and older buildings in and around St Mary's Bay often put modern windows into old walls. Perimeter joints need a sealant that suits both frame and masonry.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Questions about St Mary's Bay
Can work in a care setting near St Mary's Bay go ahead while residents are there?
Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we’ll work to them.
Does a coastal location like St Mary's Bay affect which sealant is used?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Do you check for asbestos in old sealant?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.
What paperwork can you provide?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Is St Mary's Bay in your area?
Yes. We cover St Mary's Bay, and the simplest way to start is to give us a call on 01277 525 020 or email a schedule or drawings.
Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Quoting for work in St Mary's Bay
Your fixed quote is built from the real scope. It takes account of:
- Removal of failed or old sealant
- Phasing around occupants
- Specialist products, such as fire-rated or hygienic sealants
- Site requirements such as inductions and permits
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.
Sending details for a quote
A few photographs plus some basic facts will normally do. It helps to include:
- The site address and postcode
- Anything awkward about access or site hours
- When you need the work done
- Approximate linear metres or a joint schedule
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or email drawings and photos.
Commercial clients in St Mary's Bay
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Surface by surface
Planned maintenance
We can work into your cyclical maintenance plan on a timetable you set.
External movement joints
Brickwork, blockwork and panel joints let a building move. Once that sealant goes, rain can reach the wall.
Looking after buildings in and around St Mary's Bay
St Mary's Bay lies within about 1 mile of the sea. On buildings near the shore, the side facing the weather typically needs its mastic renewed first, so it’s worth inspecting those sides more often. St Mary's Bay lies roughly 57 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate.
Churches, halls and community buildings such as All Saints are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Site managers at schools like The Marsh Academy can fit frame mastic into the summer works.
St Mary's Bay is about 6 miles south-west of Hythe, in Kent. Across the TN29 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 931 places in Kent, large and small. For work in that direction, see our Brighton page.

Diagnose, treat, sign off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a few days for most blocks, with larger programmes scheduled building by building, and we clear our waste as we work. For a site in St Mary's Bay, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- 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 sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Before we start on site
- Tell staff and tenants when we’ll be in
- Tell us your opening times and when work is allowed
- Send any specification or drawings in advance
