Mastic sealing in Cheapside, done properly
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. If you have patchy repairs in mismatched sealant and movement joints with sealant missing, we can put it right, whatever the surface. Searching for sealant specialists in Cheapside? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
For owners with a single building near Cheapside, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
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.

For managing agents and facilities managers
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Cheapside can form part of a wider programme.
Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Maintenance after handover
To get the most from the new sealant:
- Keep bins and bikes away from communal door frames
- Keep a record of when each building was resealed
- List the paperwork your organisation requires when you send details
- Start inspections with the most exposed faces
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
Joints on a building age together so a single failure is a sign to check the rest. Doing them together saves going back again and again.
Common questions from Cheapside clients
Will you take on work at estates like Ascot Business Park, close to Cheapside?
Yes. Estates, retail parks and business parks around Cheapside, Ascot Business Park among them, are all within reach. Photos and a short description are enough for a first look.
Can you quote for a block close to Ascot station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Do you do block-wide mastic programmes?
Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Which sealant will you use?
A specification, where there is one, decides it. 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.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
How do you handle work on occupied blocks?
The work is planned around occupiers. We agree the programme so you can notify occupiers and communal access is kept open.
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. Older rural buildings around Cheapside move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote once you have the details.

Block-wide mastic in Cheapside
Cheapside lies roughly 24 miles out from central London. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate. 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.
If you own or manage units on a site such as Ascot Business Park, 1.6 miles to the south-west of Cheapside, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Student accommodation around universities such as Imperial College Silwood Park Campus (0.5 miles south of Cheapside) is usually managed block by block, which suits a planned mastic programme. Blocks of flats and mixed-use buildings often cluster around stations such as Ascot station, 1.6 miles to the south-west of Cheapside, and their window and balcony mastic tends to age at the same rate across a building.

What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Failed window or door frames, which need a window contractor
If in doubt, call 01277 525 020 or email a schedule or drawings and we will say what we think.
Joints and surfaces we work on
- Window and door perimeters on blocks
- Communal entrances and stairwells

- Shopfronts below residential blocks
- Communal kitchens and washrooms
- Balcony and threshold joints
