Expansion joint sealing for commercial buildings in Jack's Hatch
Buildings and slabs are never completely still: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking and the seal across each one keeps out water and grit. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors on sites in Jack's Hatch. Site teams most often ask us about water dripping through deck or ramp joints and water getting into the wall through a failed joint, across brickwork movement joints, blockwork control joints and precast concrete panel joints. A specialist sealant contractor works differently from a general builder: on jobs in Jack's Hatch, preparation and product choice get the time they need.
Smaller community and commercial buildings around Jack's Hatch have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.
Every job we finish is backed by a 12-month workmanship guarantee, in Jack's Hatch as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Should maintenance staff do it?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
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.
Our process
At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Jack's Hatch, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Getting the site ready
- Make sure the joints can be reached
- Tell us your opening times and when work is allowed
- Arrange parking or a loading space

Do you need expansion joint sealing in Jack's Hatch?
On trafficked joints, wheels and salts do the damage. Wheel loads stress the sealant and the arrises, while de-icing salts and grit attack the seal. The product has to be suited to the traffic.
It’s worth sending us details if you spot any of the following:
- Hardened, cracked sealant on exposed facades
- Expansion joints filled with dirt and stones
- Rain penetration at brick or block movement joints
- Car park joints leaking onto vehicles below
Schools like Water Lane Primary Academy often have long brick elevations with movement joints that age quietly.

Why deal with it now?
Sealing over a failed movement joint is a common shortcut. A bead over the old seal can’t bond or flex and soon lets go. Full removal and preparation is in every quote. Halls, stores and units around places like Jack's Hatch may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

How the job changes by surface

Concrete and precast panel joints
Joints between precast panels open and close with temperature and loading. The sealant needs the right movement capability and a controlled depth.
Your questions answered
Do you cover business parks and estates near Jack's Hatch, such as Latton Bush Business Centre?
Yes. Estates, retail parks and business parks around Jack's Hatch, Latton Bush Business Centre among them, are all within reach. Photos and a short description are enough for a first look.
Is Jack's Hatch too far out for you?

Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
How long do sealant joints last?
Nobody can honestly give a figure in years, 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.
Are you fully insured?
Yes. We are fully insured, including public liability cover.
What sealant do you use in movement joints?
The specification comes first, then the joint’s movement and exposure. The quote states the sealant and its movement class so there are no surprises.
Do the joint edges need to be sound before sealing?
The edges have to be sound. Where they’ve broken up, we’ll tell you they need repairing first, so the new seal has something to grip.
