For owners and agents in Sulham
Sulham sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Sulham is about 42 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate.
Blocks of flats and mixed-use buildings often cluster around stations such as Pangbourne station, 1.4 miles to the north-west of Sulham, and their window and balcony mastic tends to age at the same rate across a building. Owners of student blocks near University of Reading (to the east of Sulham) can schedule frame and external mastic for the summer vacation.

Why it’s worth doing now in Sulham

Common questions from Sulham clients
We manage a building near Pangbourne station. Can you help?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.
Is a smaller place like Sulham outside your area?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
How long does a job like this take?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
What if the old mastic contains asbestos?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
How do you reach windows on upper floors?
Every block is different. How upper joints are reached is agreed before work is booked so there are no surprises.
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 inspection is the best way to catch problems early.
Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Check the asbestos register before any old mastic is disturbed
- Keep a record of when each building was resealed
- List the paperwork your organisation requires when you send details
- Make mastic part of routine maintenance checks
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing and the job grows.
How a job runs
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before the next one starts. For work around Sulham, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.
- We inspect each building and record the joints that have failed.
- The quote is fixed and split as suits you.

Preparing the site

Getting a fixed quote

Different surfaces, different methods
Tenement and older buildings
Older mastic can contain asbestos and the register is checked before anything is disturbed. If it’s suspected, work stops until it’s tested.
Planned maintenance
Resealing can be scheduled alongside other planned works, building by building.
