Expansion joint sealing in Apsley
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Aftercare for building managers
Cleaning and maintenance staff play a part too. Pass these on to them:
- Keep traffic off new joints until the cure time is up
- Keep stones and debris out of open joint lines
- Note which joints were done, when, and with what
- Inspect exposed joints once the cold weather has passed
Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records.
A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles. Sealing the joint promptly stops it at source.
Expansion joint sealing in Apsley, done properly
Buildings and slabs are never completely still: 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 Apsley. Site teams most often ask us about torn sealant in brick or block movement joints and leaks through car park deck joints onto the level below, on car park decks and ramps, cladding panel joints and precast concrete panel joints. Whoever orders the work in Apsley, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Rural business units around smaller places such as Apsley often have new slabs laid inside older buildings. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant.

When to bring in a specialist
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Apsley: questions and answers
Is hospital work, at somewhere like Hemel Hempstead Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Our unit in Hemel Hempstead is decades old: is it worth resealing the floor joints?
Normally, yes, as long as the joint edges are still sound. We will look at the joints, recommend a product for the traffic and movement, and say if any edges need repair before sealing.
What’s the difference between an expansion joint and a movement joint?
The general name is movement joint, and expansion joint is one common type. In everyday use the two names are often swapped.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, with one point of contact.
Can the sealant be colour-matched?
It depends on the product. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
Do you need to see the site first?
It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs typically get a visit.
Do you cover Apsley?
Yes. Sites across Apsley are covered, and the same phone number covers every area.

What else we do in Apsley
Common problems we fix in Apsley
Three-sided adhesion is a common cause of early failure. Bonded on three faces, it can’t stretch evenly when the joint opens so backing is set before sealing.
Things that typically lead to an enquiry:
- Expansion joints split through the centre of the bead
- Damp inside where a wall movement joint has failed
- Chipped joint edges on forklift routes
- Expansion joints filled with dirt and stones
On industrial estates such as Frogmore Industrial Estate, which lies east of Apsley, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.
Questions to ask before you book
- Their approach to joint depth and backing
- Their plan for phasing and protecting the area
- Do they follow the manufacturer’s priming guidance?
- Their public liability cover
How a job runs
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. For a site in Apsley, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- 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.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Getting the site ready
- Arrange parking or a loading space
- Have the specification and drawings to hand
- Move anything stored against the joints

Advice
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Concrete or masonry repairs along the arrises
- Cracking or settlement that calls for an engineer’s assessment
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
If in doubt, call the office on 01277 525 020 or send photos by email and we will say what we think before you book.

Floors, slabs and movement joints in Apsley
Apsley sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, while winter salting gets into any joint left open. Apsley is part of, or right next to, Hemel Hempstead, which was built as a planned town. With industry zoned from the outset, there’s a concentration of older warehouse floors whose joints take daily traffic; one programme for a whole row of units is often simplest.
Schools like Two Waters Primary School often have long brick elevations with movement joints that age quietly. Phasing is what makes joint work possible on busy sites such as Apsley Industrial Estate (less than half a mile south-east of Apsley): one bay, aisle or car park row at a time.

How the job changes by surface
Internal floor movement joints
Forklift and pallet-truck wheels break unsupported joint edges. We match the product to the traffic and the movement.
Car park decks and ramps
Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in.
