Expansion joint sealing for commercial buildings in The Hyde
Buildings and slabs are never completely still: they expand in the heat, shrink as they dry, and shift under load. Movement joints are where that movement is absorbed and the seal across each one keeps out water and grit. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors for buildings in The Hyde. We work on cladding panel joints, brickwork movement joints and car park decks and ramps, and what we are called in for most is new sealant over old, now failing and chipped joint edges on forklift routes. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in The Hyde, preparation and product choice get the time they need.
Around The Hyde, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. When a joint fails, grit and water get in and the arrises start to break up.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Keeping the joints sound
Once the work is signed off, these steps help:
- Look over external and deck joints after a hard winter
- Keep racking legs and heavy point loads off floor joints
- Put movement joints on the planned maintenance inspection round
- Brief car park operatives to protect joint lines during winter clearance
Fresh joint sealant needs its full cure time before it takes traffic or water. The time varies with product, conditions and joint depth, and we confirm it for each area before we leave. Keeping the area coned off until then avoids tyre marks and damage.
External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors. Catching it early keeps the water outside.
Our process
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. In The Hyde, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- First, the joints are inspected for width, movement and the type of failure.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Each joint is inspected and handed over with our 12-month guarantee.
What we need from you
- Tell us which areas need to stay in use
- Tell staff and tenants when we’ll be in
- Flag any permit to work we will need

Less than 3 miles from The Hyde there are at least three named estates and business parks. Their warehouses, yards and car parks are exactly where joints take the most punishment.

What sealant work can’t fix
We check first that sealant really is the fix. It won’t put right:
- Leaks coming from the membrane rather than the joint seal
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Cracking or settlement that calls for an engineer’s assessment
Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

The Hyde: questions and answers
Is a hospital such as BMI Hendon Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Will you take on work at estates like Silk Bridge Retail Park, close to The Hyde?
Yes. We cover The Hyde and the area around it, including industrial estates, business parks and retail parks such as Silk Bridge Retail Park. A few photos and the unit address let us price the work.
What guarantee do you give on joint sealing?
A 12-month guarantee covers our workmanship, and we’re fully insured for public liability. Regular sweeping and inspection help the joints last.
Why do our movement joints keep failing?
Usually the joint is moving more than the sealant can take. We review the joint design as well as the sealant before pricing so the same failure isn’t repeated.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards.
What happens if it rains on the day?
Sealant needs a dry joint and a temperature within the product’s range. Frost, rain and condensation on steel or concrete can hold up external work, so we plan with the forecast in mind.
How the job changes by surface
Joints between different materials
Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement.
Car park decks and ramps
Car park joints are some of the hardest-working joints in any building. A trafficable sealant suited to the movement goes in, phased so parts of the car park stay open.
Do you need expansion joint sealing in The Hyde?
With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Sealant fixed to the base and sides can’t flex, so it tears so backing is set before sealing.
Any of the following is a good reason to get the joints checked over:
- New sealant over old, now failing
- Expansion joints filled with dirt and stones
- Water dripping through deck or ramp joints
- Spalled or broken joint edges in floors and decks
At a retail site such as Silk Bridge Retail Park, less than half a mile south-east of The Hyde, joints in car parks, service yards and sales floors carry cars, cages and trolleys every day.
