About our mastic sealing in Brook Green
We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed, with backing rod setting the depth where it’s needed. Most enquiries involve mastic failing across several blocks on an estate and brittle perimeter mastic across a building, across window and door perimeters on blocks, external wall and movement joints and communal kitchens and washrooms. One point of contact handles commercial sealant work in Brook Green from the first photos to the final walk-round, for single jobs and planned programmes alike.
London’s ULEZ covers every borough, and parking and loading rules vary street by street. For a block or estate, it helps to know where we can park and stage materials.
A 12-month guarantee applies to all our work. Should something we installed fail, speak to us on 01277 525 020 or email drawings and photos and we’ll come back to it.

Brook Green: questions and answers
Do you cover business parks and estates near Brook Green, such as Berghem Mews Business Village?
Yes. Our area takes in Brook Green and its surroundings, with estates and business parks such as Berghem Mews Business Village included. A few photographs and the unit address let us price the work.
Do you work in London buildings with loading restrictions?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly.
Do you supply RAMS and insurance details?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
How do we ask for a quote?
You can use the quote form on this site; alternatively, call 01277 525 020 or use the quote form. Include photographs or drawings if you have them.

How much does the work cost?
That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we will price it properly.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
On site: what to expect
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a job in Brook Green, access comes first. Give us the hours we can be on site and we will schedule to suit.
- We check the asbestos register for older buildings and look at the joints.
- A fixed quote covers the joints, products and order of work.
- We strip out the old sealant.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
What we need from you
- Let building users know which areas are affected
- Explain the parking and delivery arrangements
- Let us know about inductions and permits

Related advice
Signs you need mastic sealing in Brook Green
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and splits as the building moves.
Typical triggers for a call:
- Cracked, hardened mastic round windows on a block
- Old repairs sealed over failed mastic
- Occupiers reporting cold air round windows
- Mastic failing across several blocks on an estate
If you manage student housing near a university such as Polish University Abroad, which lies south-west of Brook Green, the summer turnaround is the time for mastic.
Before you book anyone
- Their plan for phasing and protecting the area
- The terms of the workmanship guarantee
- Whether their applicators hold CSCS cards
- Health and safety accreditation such as CHAS
Leave it or put it right?
Dealing with failed joints one report at a time is slow and scattered. Planned resealing covers a whole building or estate in one go and is simpler to manage and budget. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

When it isn’t the sealant
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Misted or failed double-glazed units
- Water coming in from the roof or rainwater goods
- Frames that are rotten, warped or broken
Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we’ll tell you honestly.

Doing it in-house
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
