What sealant work can’t fix
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Leaks from above rather than through a joint
- Glazing that needs replacing
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

About our mastic sealing in Snaresbrook
Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Communal entrances and stairs stay usable while we work. We work on communal entrances and stairwells, communal kitchens and washrooms and window and door perimeters on blocks, and the usual reasons a site gets in touch are mastic failing across several blocks on an estate and damaged joints in communal entrances and corridors. Searching for sealant specialists in Snaresbrook? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
In a London area such as Snaresbrook, many buildings are blocks of flats or mixed-use buildings run by managing agents, landlords or housing associations. Mastic around windows, doors and balconies tends to fail across a whole block at a similar time.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Why deal with it now?
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
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, which is what makes a joint last.
Looking after the joints
A few simple habits keep the new joints working:
- Track which buildings were done and when
- Look at the sunniest and most exposed elevations first
- Protect low-level joints in entrances
- Check sealant joints during planned building inspections
Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and the complaints that come with it.
Questions we’re asked in Snaresbrook
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method.
Will you work in a care home in Snaresbrook without moving residents out?
Yes. We agree rooms and times with the manager and work a few areas at a time. We follow the home’s own procedures throughout.
Do you work in Snaresbrook?
Yes. We take on work across Snaresbrook.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
What do you charge?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we will price it properly.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
Can you reseal a whole block or estate?
We can. We survey and price each building, then work through them in order starting wherever is most urgent.
Quoting for work in Snaresbrook

- Site requirements such as inductions and permits
- The size and state of each joint
- How accessible the joints are

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
