How we handle mastic sealing in Throwley
For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card and we hold public liability insurance. Resealed mastic joints in Throwley carry our 12-month guarantee. We work on external wall and movement joints, communal entrances and stairwells and communal kitchens and washrooms, and the failures we’re asked to look at most are occupiers reporting cold air round windows and worn sealant at communal door frames. One point of contact handles commercial sealant work in Throwley from the first photographs to the final walk-round, for single jobs and planned programmes alike.
For buildings around smaller places like Throwley, we group work so one trip covers it. Photos of each elevation help us quote accurately.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Mastic sealing around Throwley: how the place shapes the job
The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first. Throwley is about 44 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.
Older community buildings, Church of St Michael and All Angels among them, often have frames of mixed ages whose mastic varies. If you look after a block within reach of Faversham station (3.6 miles north-east of Throwley), frame and balcony mastic can be renewed on one programme.
Throwley is about 4 miles south of Faversham, in Kent. If you’re looking for mastic sealing in Throwley, we can help, as we do across Kent. Throwley is one of 931 places in Kent on our list. There’s a separate page for London, about 44 miles away.

If your building is just outside Throwley, we cover Throwley Forstal (1 mile south), Sheldwich (1 mile north-east), Badlesmere (1 mile east), Sheldwich Lees (1 mile east) and Eastling (2 miles north-west). Further afield, our area takes in Maidstone (14 miles west), Ashford (9 miles south), Canterbury (10 miles east), Sittingbourne (7 miles north-west), Whitstable (10 miles north-east) and Faversham (4 miles north).

Throwley: questions and answers
We manage a building near Faversham station. Can you help?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.
Do you take on block-wide or estate-wide mastic work in Throwley?
Yes. Portfolio-wide programmes are a regular request. We can phase the programme to suit your budgets and notice periods.
Can you take on resealing for a block portfolio?
We do. 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.
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.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.
What guarantee do you give on resealing?
Our workmanship carries a 12-month guarantee and we hold public liability insurance.
What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:
- Misted or failed double-glazed units
- Frames that are rotten, warped or broken
- Leaks from above rather than through a joint
Not sure which it is? You can ring 01277 525 020 or email the details over and we’ll tell you honestly before you book.
What we seal
- Communal entrances and stairwells
- External wall and movement joints
- Shopfronts below residential blocks
- Balcony and threshold joints
- Communal kitchens and washrooms
- Window and door perimeters on blocks
General trades versus a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Diagnose, treat, sign off
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking one or more days per building, depending on the joint lengths and the access. For work around Throwley, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- We strip out the old sealant.
- Joint faces are cleaned, backed and resealed.
- Buildings are completed in turn.
Getting the site ready
- Send any specification or drawings in advance
- Share your working hours and any access restrictions
- Send asbestos survey details if the building is pre-2000

Do you need mastic sealing in Throwley?
Poor preparation explains many failed joints. Without clean, sound faces and a primer where the product needs one, the bead peels off one side.
It’s worth sending us details if you spot any of the following:
- Estate-wide sealant that is simply worn out
- Communal area joints that look neglected
- Old repairs sealed over failed mastic
- Water getting in round frames after rain
Older buildings near Throwley, from historic houses such as Belmont House and Gardens (to the north-west of Throwley) to more modest stock, need compatible products when frames are resealed.
