Expansion joint sealing in Harpsden Bottom, done properly
Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors on sites in Harpsden Bottom. Site teams most often ask us about rain penetration at brick or block movement joints and brittle, chalky sealant on external joints, on cladding panel joints, podiums and floor movement joints and precast concrete panel joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Harpsden Bottom it comes down to the same thing: the right product in a properly prepared joint.

After the work
Keep the joints in good shape with a few simple steps:
- Inspect movement joints alongside other routine building checks
- Record the sealant used and the date in the O&M file
- Check joints after long freezing spells
- Keep stones and debris out of open joint lines
Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint. Barriers left in place until then protect the finish.
Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors, well after the seal first opened. Catching it early keeps the water outside.
On site: what to expect
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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Harpsden Bottom can be grouped with others nearby. A fixed quote is given before anything starts.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.

Advice
Why act early in Harpsden Bottom
Some quotes just add sealant over the old bead. A bead laid on top of the failed one neither grips nor flexes properly. Full removal and preparation is in every quote. Halls, stores and units around places like Harpsden Bottom may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
A quote for movement joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

Harpsden Bottom: questions and answers
Is Harpsden Bottom off your patch?
No. Places such as Harpsden Bottom are covered as much as the big towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Will our site in Harpsden Bottom have to close for joint sealing?
Typically not: we work in sections and hand each one back once it has cured. We agree the sequence and timings with you before we start.
What happens if it rains on the day?
Outside work depends on conditions. Indoor joints can usually carry on regardless.
Is any job too small?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Are you fully insured?
Yes. We are fully insured, including public liability cover.
When is resealing likely to be due?
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.
What if the joint edges are damaged?
Spalled edges need repairing before a new seal will last, and we’ll point out where that’s the case. Sealing over them leads to early failure.
Cost factors for movement joints
The price varies from site to site. Expect it to depend on:
- Whether old sealant has to be cut out first
- Specialist products, such as fire-rated or hygienic sealants
- Access and working height
- Working within restricted access windows
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Details that help us quote
Good information means a firmer quote. When you get in touch, include:
- Specification clauses that apply
- Where the site is, with the postcode
- When you need the work done
- Access details, including height
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
If you are not sure, just give us a call on 01277 525 020 or email drawings and photos and we will give you a straight answer.
Joints and surfaces we work on
- Blockwork control joints

Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
