Expansion joint sealing in Whippendell Bottom, done properly
Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors on sites in Whippendell Bottom. We work on brickwork movement joints, precast concrete panel joints and blockwork control joints, and the usual reasons a site gets in touch are chipped joint edges on forklift routes and damp inside where a wall movement joint has failed. Facilities teams, main contractors and managing agents in Whippendell Bottom tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Smaller community and commercial buildings around Whippendell Bottom have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Common questions from Whippendell Bottom clients
Is a hospital such as Hemel Hempstead Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Is Whippendell Bottom too far out for you?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
How do we ask for a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
Can staff carry on working while you’re here?
Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Why deal with it now?
Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now, as damage continues meanwhile. We can split the scope into urgent and planned. Older rural buildings around Whippendell Bottom move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Why us?
- Constructionline member for supplier checks
- Fully insured
- RAL and finish matching where the product range allows
- Work carried out by CSCS-carded applicators

What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Concrete or masonry repairs along the arrises
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Damaged metal nosings or cover plates over a joint
If in doubt, give us a call on 01277 525 020 or email us and we will say what we think before you book.

Work for main contractors and building owners
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
How the job changes by surface
Brickwork and blockwork joints
Vertical movement joints in brick and block walls let the masonry grow and shrink. They take a low-modulus sealant with a movement class to suit laid over backing rod at the correct depth.
Internal floor movement joints
Forklift and pallet-truck wheels break unsupported joint edges. We match the product to the traffic and the movement.
Diagnose, treat, sign off
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. Then we strip out anything that has failed, prepare every joint and seal it. Rural sites near Whippendell Bottom may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Before we start on site
- Tell staff and tenants when we will be in
- For older buildings, check the asbestos register before work
- Explain the parking and delivery arrangements
