About our mastic sealing in Kitts End
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. 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 leaks at window and door perimeters and estate-wide sealant that is simply worn out, across shopfronts below residential blocks, communal entrances and stairwells and external wall and movement joints. For commercial sealant work in Kitts End, you deal with one contact from quote to sign-off, whether it’s one building or several.
For owners with a single building near Kitts End, we plan to finish in one visit where possible. Send photographs of the frames and joints and we’ll give a fixed quote.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Keeping the joints sound
Problems stay small when the joints are checked regularly. Specifically:
- Share the asbestos register when you send details
- Protect low-level joints in entrances
- Make mastic part of routine maintenance checks
- 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 unless told otherwise.
One failed perimeter normally means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
Planned mastic for Kitts End portfolios
The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. The 2 miles around Kitts End include three care or nursing homes. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents.
With historic buildings such as Wyllyotts Manor (to the north of Kitts End) in the wider area, owners of older properties around Kitts End should expect mastic to need a product that suits old masonry. If you look after a block within reach of Hadley Wood station, 1.1 miles to the east of Kitts End, frame and balcony mastic can be renewed on one programme. Older community buildings, Parish Church of St Mary the Virgin among them, often have frames of mixed ages whose mastic varies.

Different surfaces, different methods
Communal areas
We keep entrances and stairs open throughout. We work in sections so access is never blocked.
Estate-wide resealing programmes
Housing associations and agents often manage many similar blocks. We quote building by building and work through them in turn.
What sealant work can’t fix
Some faults sit outside our scope, and we say so rather than covering them up:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Leaks from above rather than through a joint
- Failed window or door frames, which need a window contractor
If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we’ll say what we think.
What we seal
- Balcony and threshold joints
- Communal kitchens and washrooms
- External wall and movement joints

Your questions answered
Is Kitts End off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Is Wrotham Business Park, near Kitts End, within your area?
Yes, sites like Wrotham Business Park are within our area, along with the rest of Kitts End. Send details of the unit and the work through our quote form for a quick quote.
How many days will you need on site?
It depends on the scope, but the work typically takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we will set out a timescale with the quote.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we will price the work to it.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
How do you reach windows on upper floors?
Every block is different. We agree access with you at quote stage so the fixed quote reflects it.
How a job runs
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Rural sites near Kitts End may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Preparing the site
- Let us know about inductions and permits
- Make sure the joints can be reached
- Tell staff and tenants when we will be in
Getting a fixed quote
