Mastic sealing for commercial buildings in Worth
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. We work on shopfronts below residential blocks, external wall and movement joints and balcony and threshold joints, and what we are called in for most is cracked, hardened mastic round windows on a block and old repairs sealed over failed mastic. Most enquiries from Worth start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Older buildings and conversions around places like Worth mix old masonry with newer frames. Perimeter joints need a sealant that suits both frame and masonry.
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 are clear about what is covered before work starts.

Different surfaces, different methods
Communal areas
Joints at low level in communal areas take knocks from bins, bikes and buggies and tend to fail first.
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. We look at the substrate before choosing a sealant.

What else we do in Worth
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Leaks through the frame itself rather than the perimeter
- Asbestos-containing sealant, which we don’t remove
- Masonry that has broken away beside the joint
If in doubt, speak to us on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.
Joints and surfaces we work on
- Shopfronts below residential blocks
- Window and door perimeters on blocks
- External wall and movement joints
- Balcony and threshold joints
- Communal kitchens and washrooms
- Communal entrances and stairwells
Why act early in Worth
A bead run over old mastic can look like a repair. It doesn’t bond and normally fails within a short time. Cutting out and resealing properly does it once. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Questions about Worth
Is Worth too far out for you?
No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work in a care home near Worth with residents in?
Yes, with the manager deciding the order and timing of rooms. We follow the home’s own procedures throughout.
How do we ask for a quote?
You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or send details through our quote form. Include photos or drawings if you have them.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Can you seal joints high up on a block?
We talk through access for each building when we quote. Tell us the building height and any access already in place and we’ll confirm the approach in the quote.
What will the job cost?
There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed quote.
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.
How a job runs
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a day or two for a single block, longer for an estate programme, and we clear our waste as we work. If neighbouring businesses or buildings around Worth need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Before we start on site
- Share your working hours and any access restrictions
- Send asbestos survey details if the building is pre-2000
- Point out parking and an unloading spot

Signs you need mastic sealing in Worth
The edges of the material itself sometimes break away for example where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.
Any of the following is a good reason to get the joints checked over:
- Damp patches beside frames
- Mastic failing across several blocks on an estate
- No planned programme for sealant
- Open joints in brickwork or panels
Property owners at sites such as Worth Corner Business Centre, under half a mile to the north of Worth, can have mastic renewed between lettings.
What your quote should include
- Whether their applicators hold CSCS cards
- Can the work be phased to keep areas open?
- Health and safety accreditation such as CHAS
- The named product and why it was chosen
