Block-wide mastic in Eastfields
The 2 miles around Eastfields include three care or nursing homes. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents. In London, mastic work on a block goes through the managing agent or landlord, with notice to residents. Our programme follows the access you agree with residents.
Churches, halls and community buildings such as St. Mark's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. For agents with blocks near Mitcham Eastfields station, less than half a mile south-west of Eastfields, a block-wide mastic programme deals with frames, balconies and entrances in one go. If you own or manage units on a site such as Mitcham Industrial Estate, which lies north of Eastfields, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

About our mastic sealing in Eastfields
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. Site teams most often ask us about water getting in round frames after rain and worn sealant at communal door frames, on external wall and movement joints, window and door perimeters on blocks and shopfronts below residential blocks. Whoever orders the work in Eastfields, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Across Greater London, Eastfields included, the ULEZ applies, and parking and loading rules differ from street to street. For block-wide work, a place to park and store materials saves time on every visit.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Your questions answered
Can you work in a care home near Eastfields with residents in?
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.
Does your area include sites such as Mitcham Industrial Estate, near Eastfields?
Yes. Estates, retail parks and business parks around Eastfields, Mitcham Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Is any job too small?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
What if the old mastic contains asbestos?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, ring 01277 525 020 or use the quote form. Include photographs or drawings if you have them.
Can you send RAMS and CSCS details before starting?
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 soon can the area be used again?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Why it’s worth doing now in Eastfields
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. Failed sealant in a building in Eastfields can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Why clients in Eastfields choose us
- CSCS-carded applicators
- Failed material removed, not covered up
- Public liability insurance in place
- Work to your specification and the manufacturer’s guidance

When to bring in a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off.

What affects the price in Eastfields
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Removal of failed or old sealant
- How accessible the joints are
- Location, for remote and island sites
- The total length or number of joints
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

The more we know, the firmer the quote. When you get in touch, include:
