Mastic sealing for commercial buildings in Three Mills
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. The enquiries we see most involve a mix of products and colours from past repairs and draughts at frames across a block, on external wall and movement joints, communal kitchens and washrooms and balcony and threshold joints. Searching for sealant specialists in Three Mills? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Planning mastic work on a London block means notices to residents, access to flats and agreed working areas. Work is planned with the agent so residents get notice and access is arranged in advance.
A 12-month guarantee applies to all our work. If an installation problem shows up, call the office on 01277 525 020 or send photos by email and we’ll arrange a return visit.

FAQs: Three Mills
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we will work to them.
Do you work in occupied care homes around Three Mills?
Yes. We agree rooms and times with the manager and work a few areas at a time. Tell us about any infection-control or safeguarding requirements and we will work to them.
What will the job cost?
Each job is quoted on its own details. To get one, call the office on 01277 525 020 or use the quote form.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
Is Three Mills in your area?
Yes. Sites across Three Mills are covered, with one number for every area we cover.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

What else we do in Three Mills
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Masonry that has broken away beside the joint
- Glazing that needs replacing
- Asbestos-containing sealant, which we don’t remove
If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think before you book.

- External wall and movement joints
How the job changes by surface
Planned maintenance
Planned resealing replaces emergency callouts and spreads the work.
Estate-wide resealing programmes
Using the same products throughout keeps the estate consistent and easier to manage.
How a job runs
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes one or more days per building, depending on the joint lengths and the access, and our waste is bagged and taken away as we go. Planning a London job such as one in Three Mills starts with access. Send the building rules and access times with your enquiry.
- We inspect each building and record the joints that have failed.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Failed sealant is removed and the faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
What we need from you
- Share your working hours and any access restrictions
- Point out any areas we must not close
- Make sure the joints can be reached
Ask for a quote
The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or call the office on 01277 525 020 or send photos by email to discuss it first.
Advice
For managing agents and facilities managers
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Why deal with it now?
Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. Getting scaffold, permits or access booked in Three Mills takes effort, so it makes sense to deal with every failing joint while access is in place.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Why appoint us
- Specification-led, product-correct work
- Coloured sealants to suit the setting, where available
- Clear, fixed quotes
- Fully insured
