Mastic sealing in Covent Garden, done properly
Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Communal entrances and stairs stay usable while we work. If you have worn sealant at communal door frames and failed external movement joints, we can put it right, on external wall and movement joints, balcony and threshold joints and window and door perimeters on blocks alike.

How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We inspect the joints, building by building, and record what has failed and why.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Old sealant is stripped and each face prepared back to firm material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Preparing the site

Commercial clients in Covent Garden
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Covent Garden can form part of a wider programme.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
How the quote is worked out
Your fixed quote is built from the real scope. It allows for:
- The product specified
- Whether the work must be split into stages
- The total length or number of joints
- Removal of failed or old sealant
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
Details that help us quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Any specification or named product
- Whether an asbestos survey exists
- Drawings or a marked-up plan, if available
- Any dates the work must fit around
To get a fixed quote, give us a call on 01277 525 020 or email us with the site address and an outline of the work. You can also send details through our quote form.
Honest limits
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Leaks from above rather than through a joint
- Misted or failed double-glazed units
- Leaks through the frame itself rather than the perimeter
Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we will tell you honestly before you book.
