Mastic sealing in Wennington
Managing agents and housing associations normally need paperwork before anyone starts. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are a Constructionline member and CHAS accredited, and we carry public liability insurance. We work on balcony and threshold joints, communal entrances and stairwells and shopfronts below residential blocks, and the usual reasons a site gets in touch are communal area joints that look neglected and estate-wide sealant that is simply worn out. One point of contact handles commercial sealant work in Wennington from the first photographs to the final walk-round, whether it’s one building or several.
London has a large stock of purpose-built blocks, mansion flats and converted buildings managed by agents and housing associations. Mastic around windows, doors and balconies tends to fail across a whole block at a similar time, which is why block-wide programmes make sense.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Common problems we fix in Wennington
Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant, so these repairs rarely last.
Things that typically lead to an enquiry:
- Estate-wide sealant that is simply worn out
- Water getting in round frames after rain
- Damaged joints in communal entrances and corridors
- Occupiers reporting cold air round windows
Property owners at sites such as Purfleet Industrial Park, 0.8 miles south-east of Wennington, can have mastic renewed between lettings.
Before you book anyone
- How long is the guarantee, and what does it include?
- How they’ll work around occupants
- Whether old or failed sealant will be cut out, not overlaid
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Why deal with it now?
Adding sealant to cyclical maintenance is an easy win. Waiting until leaks appear means working under pressure with less control over timing. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.

What affects the price in Wennington
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- How much existing material needs removing
- Access and working height
- Whether the work must be split into stages
- Travel to remote or island sites
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Details that help us quote
A good diagnosis starts with the right details. Let us know:
- Rough lengths or quantities, or drawings if you have them
- Clear photographs of the problem areas
- Asbestos survey details if the building is older
- Whether the building will be occupied during the work
The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or call the office on 01277 525 020 or email us to discuss it first.
Owners, agents and contractors
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

Advice
Wennington: questions and answers
Do you work for managing agents with blocks near Rainham (Essex) station?
Yes, we work for agents, landlords and housing associations with blocks of every size. We work to your notice and access arrangements.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we will plan accordingly. We allow for the ULEZ, which covers every borough
Do you work with property factors and landlords?
Yes, that’s exactly who this service is for. We work through buildings in a planned order so you can plan around it.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Can you seal joints high up on a block?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
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.

After the work
Problems stay small when the joints are checked regularly. In particular:
- Look at the sunniest and most exposed elevations first
- Protect low-level joints in entrances
- Have the asbestos survey to hand for older buildings
- Include mastic in your cyclical inspections
Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.
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.
