How we handle mastic sealing in Lisson Grove
Managing agents and housing associations usually need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are a Constructionline member and CHAS accredited, and we carry public liability insurance. Site teams most often ask us about movement joints with sealant missing and old repairs sealed over failed mastic, on communal kitchens and washrooms, shopfronts below residential blocks and balcony and threshold joints. Facilities teams, main contractors and managing agents in Lisson Grove tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For managing agents in Lisson Grove, 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.
Work we carry out in Greater London comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

Our process
Tell us your site hours and access windows and we’ll plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Planning a London job such as one in Lisson Grove starts with access. Give us the hours we can be on site and we will schedule to suit.
- First comes a look at the joints and, for older buildings, the asbestos records.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- Buildings are completed in turn.
Preparing the site
- Flag any permit to work we will need
- Arrange parking or a loading space
- Clear stock, furniture or equipment away from the joints
Ask for a quote
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or email a schedule or drawings with what you know.
Advice
Surface by surface
Estate-wide resealing programmes
An estate of similar buildings suits a rolling programme. Each block is priced and scheduled in order.
Communal areas
Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Fresh joints make shared areas look looked after.
Block-wide mastic in Lisson Grove
London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. We fit the programme to your notice periods.
Churches, halls and community buildings such as St Paul's Community Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Property owners at sites such as The Quadrant Business Centre (1.9 miles north-west of Lisson Grove) can have mastic renewed between lettings. For a school such as Gateway Academy, perimeter mastic on windows and doors is a holiday job.

Quoting for work in Lisson Grove
There’s no standard rate for sealant work, because every site is different. What we look at:
- Which sealant the job calls for
- Access and working height
- Phasing around occupants
- Site requirements such as inductions and permits
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
Sending details for a quote
Whether it’s one area or a whole building, these details speed things up:
- Any dates the work must fit around
- The site address and postcode
- Rough lengths or quantities, or drawings if you have them
- Whether an asbestos survey exists
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to give us a call on 01277 525 020 or send details through our quote form.
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.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Questions about Lisson Grove
Can you cope with the access rules in a London building?
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. The ULEZ covers the whole of Greater London, which we allow for
Do you work for managing agents with blocks near London Marylebone station?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
How long does a job like this take?
It depends on the scope, but the work usually takes anything from a day to a few weeks, depending on the number of buildings and joints. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- Track which buildings were done and when
- Group repairs into a planned programme
- Start inspections with the most exposed faces
- Share your contractor requirements early
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing.
