Mastic sealing for Maryland sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Common problems we fix in Maryland
Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope and fails early.
Clients usually get in touch after noticing something like this:
- Repeated reactive repairs to the same buildings
- Draught complaints from residents or tenants
- Brittle perimeter mastic across a building
- Mastic failing across several blocks on an estate
Buildings close to stations like Stratford (London) station, under half a mile to the south-west of Maryland, are often flats over shops, with frame mastic to keep sound.

Mastic sealing for commercial buildings in Maryland
We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. We work on external wall and movement joints, communal entrances and stairwells and window and door perimeters on blocks, and what we are called in for most is movement joints with sealant missing and water getting in round frames after rain. Facilities teams, main contractors and managing agents in Maryland tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Across Greater London, Maryland 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.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Cost factors for mastic joints
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- How accessible the joints are
- Specialist products, such as fire-rated or hygienic sealants
- Site requirements such as inductions and permits
- Distance, for remote addresses
The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.
Before you send an enquiry
We can often quote from photographs and a few details. It helps to include:
- Your programme or deadline
- Whether an asbestos survey exists
- How the joints are reached, and at what height
- Specification clauses that apply
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.
Frames, entrances and external joints in Maryland
Maryland has 25 care or nursing homes no more than 2 miles away. Owners of care premises can bring window and door mastic into a phased programme planned around the home. For a London block, the agent or landlord typically handles notices to residents and access to flats. We fit the programme to your notice periods.
Older buildings near Maryland, from historic houses such as Sutton House, 2.1 miles west of Maryland, to more modest stock, need compatible products when frames are resealed. For owners of several units at places like Maryland Industrial Estate, 0.5 miles to the north-east of Maryland, one programme can deal with frame and external mastic across the lot.
Maryland is about 3 miles south of Walthamstow, in Greater London. We send applicators to Maryland for mastic joints. Our Greater London coverage takes in 764 places.
Commercial sites across E15, E20 and E7 are covered for mastic joints. If your site is on Cam Road, Ward Road and Wise Road or close by, we can quote for mastic joints. If your building is just outside Maryland, we cover Stratford (1 mile west), East Village (1 mile north-west), Temple Mills (1 mile north-west), West Ham (1 mile south-east) and Holloway Down (1 mile north). Further afield, our area takes in London (5 miles south-west), City of Westminster (7 miles west), Marylebone (6 miles west), Kensington (9 miles west), St Pancras (5 miles west) and Shoreditch (3 miles west).
Local landmarks in Maryland

For a walk, there’s Old Ford Island and Hollow Pond.
What else we do in Maryland
Maryland: questions and answers
Do you work for managing agents with blocks near Stratford (London) station?
Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.
Will you work in a care home in Maryland without moving residents out?
Yes, with the manager deciding the order and timing of rooms. We follow the home’s own procedures throughout.
Do you cover Maryland?
Yes. We take on work across Maryland, with one number for every area we cover.
Do you guarantee the mastic work?
Our workmanship carries a 12-month guarantee and we hold public liability insurance.
Do you supply RAMS and insurance details?
We’re CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
How do you choose the sealant?
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.
Different surfaces, different methods
External movement joints
The joint width has to suit the movement and the sealant’s capability with the width-to-depth ratio set as the manufacturer advises.
Estate-wide resealing programmes
An estate of similar buildings suits a rolling programme. We quote building by building and work through them in turn.
Leave it or put it right?
A bead run over old mastic can look like a repair. It doesn’t bond and normally fails within a short time. Full removal and proper preparation is what lasts. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Honest limits
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Water coming in from the roof or rainwater goods
- Materials that need asbestos testing before work
- Leaks through the frame itself rather than the perimeter
Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

- Communal entrances and stairwells
- Communal kitchens and washrooms

Our process
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Planning a London job such as one in Maryland starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
Getting the site ready
- Send asbestos survey details if the building is pre-2000
- Send any specification or drawings in advance
- Make sure the joints can be reached
