Mastic sealing for commercial buildings in Summerstown
Owners and agents normally inherit a building’s mastic rather than choose it and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. If you have failed external movement joints and occupiers reporting cold air round windows, we can put it right, whatever the surface. For commercial sealant work in Summerstown, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
London has a large stock of purpose-built blocks, mansion flats and converted buildings managed by agents and housing associations. Window and door perimeters, balcony joints and communal areas all have mastic that ages together across a building, which is why block-wide programmes make sense.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

How a job runs
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts.

- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- We agree the programme and dates with you.
- Failed sealant is removed and the faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.

Your questions answered
Will you work in a care home in Summerstown without moving residents out?
Yes. We agree rooms and times with the manager and work a few areas at a time. Noise and disruption are kept to a minimum.
Do you work in London buildings with loading restrictions?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Share the building’s contractor rules and we’ll work to them. All of Greater London is inside the ULEZ, and our planning allows for it
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure.
Can you take on resealing for a block portfolio?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Can you seal joints high up on a block?
Every block is different. We agree access with you at quote stage so the fixed quote reflects it.
What sealant work can’t fix
We check first that sealant really is the fix. It won’t put right:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Frames that are rotten, warped or broken
- Misted or failed double-glazed units
If you are not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.
What we seal
- Balcony and threshold joints
- External wall and movement joints
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- Window and door perimeters on blocks
- Communal entrances and stairwells
Mastic sealing around Summerstown: how the place shapes the job
Six care or nursing homes sit less than 2 miles from Summerstown. Care home owners need frame and external mastic kept sound without unsettling residents. Blocks in London are typically run by managing agents, landlords or housing associations, with residents to notify and access to arrange. Our programme follows the access you agree with residents.
Older community buildings, St Mary's Church among them, often have frames of mixed ages whose mastic varies. If you manage student housing near a university such as Kingston University Roehampton Vale Campus, 2.8 miles to the west of Summerstown, the summer turnaround is the time for mastic. Blocks of flats and mixed-use buildings often cluster around stations such as Earlsfield station (to the north of Summerstown) and their window and balcony mastic tends to age at the same rate across a building.

Building owners, agents and FMs in Summerstown
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.
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Summerstown. Several sites can go on one quote, which keeps the paperwork simple.
Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
How the quote is worked out
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Which sealant the job calls for
- Travel to remote or island sites
- The size and state of each joint
- How much existing material needs removing
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
Sending details for a quote
A few photos plus some basic facts will normally do. It helps to include:
- Whether an asbestos survey exists
- Drawings or a marked-up plan, if available
- Any specification or named product
- The postcode of the building
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call 01277 525 020 or email drawings and photos.
