Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Include mastic in your cyclical inspections
- Encourage occupiers to report problems at frames
- Look at the sunniest and most exposed elevations first
- Keep a record of when each building was resealed
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
One failed perimeter usually means others on the same building are close, so it pays to look at the whole elevation. Doing them together saves going back again and again.
Quoting for work in Crofton Park
What shapes the price:
- Location, for remote and island sites
- The total length or number of joints
- Which sealant the job calls for
- How accessible the joints are
Whether it’s a single area or a whole estate, the same things set the price: 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.
Sending details for a quote
A good diagnosis starts with the right details. Let us know:

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or send photos by email with what you know.

Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a job in Crofton Park, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.

What the job involves on each surface
Commercial and mixed-use buildings
Landlords with commercial portfolios have shopfronts, office entrances and external joints to look after. A planned programme suits multi-building portfolios.
Planned maintenance
Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Regular inspection is the best way to plan resealing.
When it isn’t the sealant
Being straight saves everyone time. Fresh joints won’t solve:
- Masonry that has broken away beside the joint
- Leaks from above rather than through a joint
- Failed window or door frames, which need a window contractor
If you’re not sure, just call the office on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.
Where we work in Crofton Park
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- External wall and movement joints
- Communal entrances and stairwells
- Balcony and threshold joints
- Window and door perimeters on blocks
