Mastic sealing for commercial buildings in Sutton Common
On a residential block, the work happens around people’s lives. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Entrances and stairwells are kept in use while we work. The enquiries we see most involve the same joint failures repeated across a portfolio and worn sealant at communal door frames, across communal kitchens and washrooms, communal entrances and stairwells and external wall and movement joints. A single leaking joint is often how a building in Sutton Common first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Planning mastic work on a London block means notices to residents, access to flats and agreed working areas. We work to the agent’s notice and access plan, so residents know what’s happening.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What we can’t put right
Honesty saves time and money. Fresh joints won’t solve:
- Water coming in from the roof or rainwater goods
- 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 you’re not sure, just call 01277 525 020 or send photos by email and we will give you a straight answer.
Joints and surfaces we work on
- Balcony and threshold joints
- External wall and movement joints
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Shopfronts below residential blocks
- Window and door perimeters on blocks
Why it’s worth doing now in Sutton Common
Failed perimeter mastic lets cold air in around frames and the windows typically get the blame. Resealing the perimeters is often the simpler fix when the frames themselves are sound. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Looking after buildings in and around Sutton Common
In London, mastic work on a block goes through the managing agent or landlord, with notice to residents. Our programme follows the access you agree with residents. Sutton Common has three care or nursing homes no more than 2 miles away. Care home owners need frame and external mastic kept sound without unsettling residents.
If you’re responsible for a building such as St Lawrence Church, frame and door mastic needs the same attention as any other property. If you look after a block within reach of St Helier station, which lies north of Sutton Common, frame and balcony mastic can be renewed on one programme.

Your questions answered
Can you work in a care home near Sutton Common with residents in?
Yes. We work around residents’ routines, a room or two at a time. Tell us about any infection-control or safeguarding requirements and we will work to them.
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
What will the job cost?
Each job is quoted on its own details. To get one, phone 01277 525 020 or email drawings and photos.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Can you quote from photographs?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Quoting for work in Sutton Common

- Any access equipment needed
- Whether old sealant has to be cut out first
- Joint width, depth and condition
- The site’s rules and procedures
We don’t publish prices, since every building and every scope is different. Call for a quote and we will price your job on its own details.
Details that help us quote
We can often quote from photos and a few details. Please tell us:
- The postcode of the building
- Asbestos survey details if the building is older
- Approximate linear metres or a joint schedule
- A wide shot and a close-up of the area
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
Work for main contractors and building owners
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

When to call us in Sutton Common
Buildings move with temperature and moisture, and the sealant takes up that movement. If the joint or the product wasn’t suited to the movement, it splits long before it should.
Most enquiries start with something like this:
- Failed external movement joints
- Communal area joints that look neglected
- Draught complaints from residents or tenants
- Window mastic that has split and shrunk
If your remit includes a building such as Abbey Primary School, frame and door mastic can be programmed for the holidays.
What your quote should include
- Whether primer will be used where the manufacturer specifies it
- How they handle RAMS and site documents
- Health and safety accreditation such as CHAS
- What level of public liability insurance do they hold?
Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly.

- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
