What sets the cost
We price every job individually. The main factors are:
- Quantities, in metres or numbers
- Specialist products, such as fire-rated or hygienic sealants
- Whether old sealant has to be cut out first
- The site’s rules and procedures
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
What to include in your enquiry
To price the job accurately, we need to understand the site. Useful things to include:
- Photos of the joints, close up and from further back
- How the joints are reached, and at what height
- Whether an asbestos survey exists
- The postcode of the building
For a fixed quote, phone 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. Our quote form is another easy route.
Different surfaces, different methods
Brickwork and blockwork joints
Long brick and block elevations have movement joints at intervals. They take a low-modulus sealant with a movement class to suit, with backing rod setting the depth.
Concrete and precast panel joints
Concrete edges can be weak or carry release agents that stop adhesion. Proper cleaning and primer where specified give a sound bond and check the edges for soundness as we go.
Common problems we fix in Letchmore Heath
The edges of the material can fail rather than the sealant. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip.
Clients typically get in touch after noticing one or more of the following:
- New sealant over old, now failing
- Weathered movement joint sealant that no longer flexes
- Arrises breaking up along floor joints
- Car park joints leaking onto vehicles below
Schools like Fair Field Junior School often have long brick elevations with movement joints that age quietly.
Questions to ask before you book
- What the guarantee covers, and for how long
- How joint depth will be controlled
- Will CSCS-carded applicators be on site?
- Whether primer will be used where the manufacturer specifies it
From enquiry to sign-off
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Letchmore Heath may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- 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.
- 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
- Flag any permit to work we will need
- Arrange parking or a loading space
- Let building users know which areas are affected

Related advice
Keeping the joints sound
Regular inspection catches problems early. Specifically:
- Check joints after long freezing spells
- Keep stones and debris out of open joint lines
- Brief car park operatives to protect joint lines during winter clearance
- Leave barriers in place until fresh joint sealant has cured
Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records, so the next reseal starts with the facts.
A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it. Sealing the joint promptly stops it at source.
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. A poor seal in places like these tends to cost more to put right later.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
