Cost factors for movement joints
The price varies from site to site. It mainly depends on:
- Joint width, depth and condition
- Removal of failed or old sealant
- The total length or number of joints
- Whether the work must be split into stages
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
Sending details for a quote
However big the job, the same details help:
- Whether the building will be occupied during the work
- Whether an asbestos survey exists
- Your programme or deadline
- How the joints are reached, and at what height
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Expansion joint sealing in Hitchin, done properly
A movement joint only works while its seal does. Once it fails, water, grit and debris get in. Resealing at the first signs of failure is far cheaper than repairing the material either side. We work on cladding panel joints, blockwork control joints and car park decks and ramps, and the failures we are asked to look at most are torn sealant in brick or block movement joints and rain penetration at brick or block movement joints. Searching for sealant specialists in Hitchin? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
In Hitchin, as in most towns, brickwork and panel movement joints on public and commercial buildings age quietly. Once the sealant hardens or splits, water gets into the wall and the joint no longer works.
A 12-month guarantee applies to all our work. If an installation problem shows up, phone 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

How soon can the area be used again?
Curing time varies by product, and we confirm it on the day.
Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a town like Hitchin, we try to group jobs for the same client into one visit, with one quote covering them. Tell us when the building is open and we’ll plan to suit.
- We look at the joints, their width and how they’ve failed.
- You get a fixed quote with the product and its movement capability stated.
- We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.

Related advice
Why it’s worth doing now in Hitchin
Leaving a failed movement joint rarely stays a small problem. Water and debris get in, the joint jams and the edges spall, so a reseal turns into an edge repair as well. Resealing early keeps the work to sealant. In a town like Hitchin, a split, stained or mouldy joint is often the first thing visitors notice. Fresh sealant makes a building look maintained.
The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote once you have the details.

At about 32 miles from central London, Hitchin is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open.
For an estate such as Pinehill Hospital (less than half a mile east of Hitchin), the joints in ramps, decks and long building elevations all need attention over time.

More services for Hitchin
Do you need expansion joint sealing in Hitchin?
Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600, and specifications often refer to it.
Common reasons buildings call us in:
- Torn sealant in brick or block movement joints
- Rain penetration at brick or block movement joints
- Joints packed with grit and debris
- Chipped joint edges on forklift routes
For a school such as Hitchin Girls' School, playground and building joints can be done in the holidays.
Before you book anyone
- Who will actually carry out the work
- Is the sealant right for the movement and the substrate?
- How joint depth will be controlled
- How long is the guarantee, and what does it include?
Maintenance after handover
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Plan racking layouts so feet don’t land on a joint
- Reopen bays and walkways only after the stated cure time
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Treat a small split as a warning, not a cosmetic issue
In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints.
On a multi-storey car park, a failed joint normally shows up as a leak onto the deck underneath. That water often carries de-icing salts with it. Resealing early limits the damage.
Surface 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.
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 laid over backing rod at the correct depth.
