For owners and agents in Bishop's Sutton
Bishop's Sutton is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. At about 53 miles from central London, Bishop's Sutton is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate.
If you are responsible for a building such as Church of St Nicholas, frame and door mastic needs the same attention as any other property. Schools and community buildings such as Perins School need frame and external mastic kept sound like any building.

About our mastic sealing in Bishop's Sutton
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. The enquiries we see most involve old repairs sealed over failed mastic and leaks at window and door perimeters, on shopfronts below residential blocks, window and door perimeters on blocks and balcony and threshold joints. A single leaking joint is often how a building in Bishop's Sutton 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.
For owners with a single building near Bishop's Sutton, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you.

- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.

When it isn’t the sealant
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Masonry that has broken away beside the joint
- Frames that are rotten, warped or broken
- Leaks from above rather than through a joint
Not sure which it is? You can phone 01277 525 020 or email the details over and we’ll tell you honestly.
Joints and surfaces we work on
- Window and door perimeters on blocks
- Balcony and threshold joints
- Communal kitchens and washrooms
- External wall and movement joints
- Shopfronts below residential blocks
- Communal entrances and stairwells
What happens if it’s left?
Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes and those cost far more to put right. Converted and older buildings near places like Bishop's Sutton tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
A quote for mastic joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

What sets the cost
A fixed quote reflects the actual work. It takes account of:
- The total length or number of joints
- Site requirements such as inductions and permits
- Backing rod, priming and other preparation
- Phasing around occupants
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
What to include in your enquiry
A good diagnosis starts with the right details. Tell us:

- Access details, including height
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to call the office on 01277 525 020 or send photos by email.
Do you need mastic sealing in Bishop's Sutton?
UV and rain age external sealant. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.
Any of the following is a good reason to get the joints checked over:
- Estate-wide sealant that is simply worn out
- Damp patches beside frames
- A mix of products and colours from past repairs
- Occupiers reporting cold air round windows
Older buildings near Bishop's Sutton, from historic houses such as Hinton Ampner House, 2.9 miles to the south of Bishop's Sutton, to more modest stock, need compatible products when frames are resealed.
What your quote should include
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Is the sealant right for the movement and the substrate?
- Whether their applicators hold CSCS cards
- Are they CHAS accredited or on Constructionline?
Common questions from Bishop's Sutton clients
Will you price a mastic programme across our Bishop's Sutton portfolio?
Yes. Portfolio-wide programmes are a regular request. We can phase the programme to suit your budgets and notice periods.
What paperwork can you provide for a job in Bishop's Sutton?
We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.
Is asbestos a concern with old mastic?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Do you cover Bishop's Sutton?
Yes. Bishop's Sutton is in our area, within our coverage of Greater London, South East England and Scotland. For a quote, ring 01277 525 020 or email the details over.
