About our mastic sealing in East Wickham
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 and backing rod used wherever a joint is deep. The enquiries we see most involve movement joints with sealant missing and cracked, hardened mastic round windows on a block, across external wall and movement joints, communal kitchens and washrooms and window and door perimeters on blocks. Most enquiries from East Wickham start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For managing agents in East Wickham, resident access, notice periods and the building’s rules shape the job. We work to the agent’s notice and access plan, so residents know what’s happening.
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.

What sets the cost
We price every job individually. The things that drive the figure:
- Backing rod, priming and other preparation
- Site requirements such as inductions and permits
- Quantities, in metres or numbers
- Working within restricted access windows
Pricing mastic joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.
Details that help us quote
It doesn’t need to be a full survey. These details are enough to start:
- The postcode of the building
- The product your specification calls for
- Anything awkward about access or site hours
- Drawings or a marked-up plan, if available
Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. If you have questions first, give us a call on 01277 525 020 or send photos by email.
Building owners, agents and FMs in East Wickham
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in East Wickham can sit alongside others in a wider programme.
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a job in East Wickham, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.
- We check the asbestos register for older buildings and look at the joints.
- A fixed quote covers the joints, products and order of work.

Advice
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.
A short, simple internal joint is often within reach of a maintenance team. 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.
How the job changes by surface
Planned maintenance
Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Inspecting joints regularly keeps programmes on track.
Communal areas
Communal areas stay in use while we work. Work is planned in sections.
Your questions answered
Will you work in a care home in East Wickham without moving residents out?
Yes, with the manager deciding the order and timing of rooms. Noise and disruption are kept to a minimum.
Does your area include sites such as Gateway Business Centre, near East Wickham?
Yes. Our area takes in East Wickham and its surroundings, with estates and business parks such as Gateway Business Centre included. To start, just speak to us on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
How many days will you need on site?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Looking after buildings in and around East Wickham
The 2 miles around East Wickham include two care or nursing homes. Owners of care premises can bring window and door mastic into a phased programme planned around the home. London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. We work to your notice and access plan.
Blocks of flats and mixed-use buildings often cluster around stations such as Welling station (under half a mile south-east of East Wickham) and their window and balcony mastic tends to age at the same rate across a building. Property owners at sites such as Gateway Business Centre (to the north of East Wickham) can have mastic renewed between lettings. If you manage student housing near a university such as University of Greenwich Avery Hill Campus (1.8 miles south-west of East Wickham), the summer turnaround is the time for mastic.

What sealant work can’t fix
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Failed window or door frames, which need a window contractor
- Leaks from above rather than through a joint
- Broken glass or failed sealed units
If in doubt, phone 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.
Surfaces we seal
- Window and door perimeters on blocks
- External wall and movement joints
- Shopfronts below residential blocks
- Balcony and threshold joints
- Communal entrances and stairwells
- Communal kitchens and washrooms
