Mastic sealing in Walter's Green, done properly
Before work starts, most agents and landlords want the documents in order. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. We work on balcony and threshold joints, external wall and movement joints and communal kitchens and washrooms, and the usual reasons a site gets in touch are complaints coming in block by block and leaks at window and door perimeters. Facilities teams, main contractors and managing agents in Walter's Green tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Owners and agents with buildings around smaller places such as Walter's Green tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

When to call us in Walter's Green
Much failed sealant was laid on dirty, dusty or damp surfaces. Without clean, sound faces and a primer where the product needs one it comes away from one face.
Clients normally get in touch after noticing something like this:
- Estate-wide sealant that is simply worn out
- No planned programme for sealant
- Movement joints with sealant missing
- Water getting in round frames after rain
If you’re responsible for a building such as Church of St Peter, frame and door mastic needs the same attention as any other property.
What your quote should include
- How they’ll work around occupants
- What level of public liability insurance do they hold?
- Whether primer will be used where the manufacturer specifies it
- Whether old or failed sealant will be cut out, not overlaid
Walter's Green: questions and answers
Do you work for managing agents with blocks near Ashurst Kent station?
Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.
Is a smaller place like Walter's Green outside your area?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How long does a job like this take?
That varies with the scale of the job, but the work usually takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we will set out a timescale with the quote.
Can you reseal a whole block or estate?
Yes. We survey and price each building, then work through them in order starting wherever is most urgent.
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.
Is mastic sealing guaranteed?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
Honest limits
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Glazing that needs replacing
- Failed window or door frames, which need a window contractor
Not sure which it is? You can call 01277 525 020 or email the details over and we’ll tell you honestly.
Joints and surfaces we work on
- Balcony and threshold joints
- Communal entrances and stairwells
- Shopfronts below residential blocks
- Window and door perimeters on blocks
- External wall and movement joints
- Communal kitchens and washrooms

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. For a building around Walter's Green, tell us how to find it and who will meet us.

Doing it in-house
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Block-wide mastic in Walter's Green
Walter's Green is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first. Walter's Green is about 27 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.
Student accommodation around universities such as Canterbury Christ Church University - Salomons, 3.5 miles to the east of Walter's Green, is usually managed block by block, which suits a planned mastic programme. Site managers at schools like Fordcombe Church of England Primary School can fit frame mastic into the summer works.

Why act early in Walter's Green
Sealing over failed mastic looks tidy for a while. It doesn’t bond and typically fails within a short time. Cutting out and resealing properly does it once. For buildings around smaller places like Walter's Green, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Why appoint us
- Clear, fixed quotes
- Standard and matched colours in many product ranges
- CHAS accredited contractor
- Fully insured
Keeping the joints sound
To get the most from the new sealant:
- Share the asbestos register when you send details
- Keep bins and bikes away from communal door frames
- Start inspections with the most exposed faces
- Group repairs into a planned programme
If paintable sealant was used, decoration can follow once it has cured. Silicone typically can’t be painted, so keep decorators off it.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
