Construction mastic in Brook Green, done properly
Mastic tends to be one of the final packages before handover, which puts it right on the critical path. Mastic Doctor takes on mastic packages for main contractors and developers. If you have cracks opening in caulked internal joints and early adhesion failures on new external joints, we can put it right, on internal decorators’ caulk, cladding and panel joints and sanitary and kitchen joints alike. Searching for sealant specialists in Brook Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Brook Green must meet its standards or pay the daily charge. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.

How a job runs
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. All of Greater London is in the ULEZ, and kerbside space in Brook Green can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- Drawings, specification and programme come to us.
- Quantities are measured and a fixed price returned.
- The sequence is agreed with the site manager.
- Each area is sealed when it’s released.
- Every joint is cleaned, set to depth and sealed with the specified product.
- After snagging, the work is handed over under our 12-month guarantee.
Preparing the site
- Make sure the joints can be reached
- Tell staff and tenants when we will be in
- Tell us what induction or permit system the site runs

Construction mastic in Brook Green: the local picture
The ULEZ covers the whole of Greater London, Brook Green included, so site vehicles need to meet its standards or pay the daily charge. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. Brook Green has a good number of hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
Work at a hotel such as Brook Green Hotel (under half a mile north-west of Brook Green) tends to be programmed around bookings, mastic included. Hospital estates such as Charing Cross Hospital (to the south of Brook Green) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
Brook Green is about 1 mile west of Kensington, in Greater London. Brook Green sits inside our coverage and the rest of Greater London, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 764 places in Greater London, large and small.
Commercial sites across W6, W14 and W12 are covered for mastic packages. If your site is on Adie Road, Rowan Road and Anley Road or close by, we can quote for mastic packages. If your building is just outside Brook Green, we cover Hammersmith (1 mile west), Brackenbury Village (1 mile west), North End (1 mile south-east), West Kensington (1 mile south-east) and Fulham (1 mile south-east).

Common problems we fix in Brook Green
Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly so we set the depth properly before sealing.
Clients usually get in touch after noticing one or more of the following:
- A long mastic snag list close to completion
- Sealant knocked or painted over by other trades
- External joints sealed in damp or cold conditions that are now failing
- Oversized or tapered gaps around new frames
Projects at colleges like St Mellitus Theological College, 1.4 miles east of Brook Green, tend to run to term dates, so the mastic is planned tightly.
What your quote should include
- How long is the guarantee, and what does it include?
- Their pre-qualification and accreditations
- Can the work be phased to keep areas open?
- Their public liability cover
What sets the cost
To price the job, we consider:
- Removal of failed or old sealant
- Quantities, in metres or numbers
- Which sealant the job calls for
- Backing rod, priming and other preparation
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 and we will explain how it’s made up.
Details that help us quote
A good diagnosis starts with the right details. Tell us:
- Rough lengths or quantities, or drawings if you have them
- Whether the building will be occupied during the work
- The postcode of the building
- Specification clauses that apply
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Questions we are asked in Brook Green
Do you work in London buildings with loading restrictions?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Can you work at a site such as Berghem Mews Business Village, by Brook Green?
Yes. Estates, retail parks and business parks around Brook Green, Berghem Mews Business Village among them, are all within reach. To start, just give us a call on 01277 525 020 or email us with the unit, the joints involved and your access times.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Can the sealant be colour-matched?
That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
When it isn’t the sealant
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Oversized gaps that need packing or adjustment by others
- Approving fire stopping as compliant
- Defective windows, doors or glazing units (the supplier or installer’s job)
Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.
Where we work in Brook Green

Maintenance after handover
After handover, a little attention goes a long way:
- Put any product change through the designer first
- Ask cleaners to use soft cloths around fresh sealant
- Get the mastic subcontractor involved early in the programme
- Keep product details for future maintenance
After we have sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby, and that time depends on the product, temperature and joint depth.
Snag items left to the last week put handover at risk. A planned close-out through each area as it completes keeps the list short and keeps handover on track.
