Facade sealing across Maryland
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How a job runs
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes a day or two for a few elevations, and longer where access has to be moved around the building. All of Greater London is in the ULEZ, and kerbside space in Maryland can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
What we need from you
- Move anything stored against the joints
- Explain the parking and delivery arrangements
- Flag any permit to work we’ll need

Facade sealing in Maryland
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure on offices, blocks and industrial units. Coping and flashing joints are included where sealant is the specified fix. We work on window and door perimeters, stone and brick facade joints and perimeter joints where frames meet the structure, and the failures we’re asked to look at most are new sealant peeling off old mastic and old perimeter mastic that has dried out. For commercial sealant work in Maryland, you deal with one contact from quote to sign-off, whether it’s one building or several.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Maryland 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.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

What sets the cost
The price varies from site to site. It mainly depends on:
- Working within restricted access windows
- The product specified
- Joint width, depth and condition
- Any access equipment needed
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
Sending details for a quote
There’s no need for a formal survey. A few details are enough to get going:
- Specification clauses that apply
- Access details, including height
- The type of building and who uses it
- When you need the work done
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
For managing agents and facilities managers
Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Questions we are asked in Maryland
Do you take on work at healthcare sites like Homerton University Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
Do you install glazing systems?
No. That work needs a glazing specialist. We reseal window perimeters, panel joints and frame-to-structure perimeters.
When is resealing likely to be due?
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.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs normally get a visit.
Are you fully insured?
Yes. We’re fully insured, and the certificate can go with your quote.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Sites and facades in and around Maryland
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Maryland. Deliveries are booked and storage is tight, so mastic materials come in as needed. Maryland has a good number of hotels close by, all within 2 miles. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
For contractors refurbishing units at places like Maryland Industrial Estate, which lies north-east of Maryland, the mastic covers cladding panels, roller-door and window perimeters. Projects at colleges like Ebrahim College (under half a mile south of Maryland) tend to run to term dates, so the mastic is planned tightly. Hospital estates such as Homerton University Hospital, 2 miles west of Maryland, 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.
Maryland is about 3 miles south of Walthamstow, in Greater London. Commercial clients in Maryland can call on us for facade joints. We work across 764 places in Greater London, from busy centres to rural villages.
Work on facade joints is covered throughout E15, E20 and E7. Streets here include Cam Road, Ward Road and Wise Road, and sites on any of them can send details for a fixed quote. We also 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
Recent enquiries here include premises near Sarah Bonnell School, West Ham Park and Carpenters Primary School and the streets around them. There’s a railway station in Maryland itself: Stratford (London) station. A little further out are Passmore Edwards Museum (0.5 miles east) and Tower of London (4 miles south-west). Green spaces nearby include Old Ford Island and Hollow Pond.
Why deal with it now?
Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Other services in Maryland
Doing it in-house
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. That’s why many clients bring in a specialist from the beginning.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Different surfaces, different methods
Perimeter joints at frames and structure
Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. We seal those perimeter joints.
Brick and stone facades
Brick and stone facades have perimeter and movement joints that need a compatible sealant. We avoid acetoxy silicone, which can stain some natural stone, and primers go on where specified.
