Expansion joint sealing in Hempstead: the local picture
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. At about 41 miles from central London, Hempstead is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds; their floors carry heavy traffic every shift.
Hospital campuses such as Saffron Walden Community Hospital (to the west of Hempstead) grow in stages, leaving movement joints wherever new blocks meet old.

Expansion joint sealing in Hempstead
Our movement joint work takes in walls, panels, decks and floors: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. The product depends on the movement, the weather and anything that runs over it. We work on blockwork control joints, precast concrete panel joints and cladding panel joints, and the failures we are asked to look at most are sealant pulling off the joint face and chipped joint edges on forklift routes. Searching for sealant specialists in Hempstead? We’ve been sealing commercial buildings since 2005.
Around smaller places such as Hempstead, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Honest limits
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Changing the joint layout or spacing of a structure
- Proprietary pre-formed expansion joint systems

FAQs: Hempstead
Is Hempstead off your patch?
No. Places such as Hempstead are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Does a site in Hempstead have to shut while its joints are sealed?
Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we’ll plan from there.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Do the joint edges need to be sound before sealing?
The edges have to be sound. Where they’ve broken up, we will tell you they need repairing first so you’re not paying for a bead that won’t hold.
Which product is best for expansion joints?
The specification comes first, then the joint’s movement and exposure. The quote states the sealant and its movement class, so you know what’s going in.
On site: what to expect
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, and we clear our waste as we work. For work around Hempstead, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- First, the joints are inspected for width, movement and the type of failure.
- Next, we fix a price and confirm the sealant we propose for the movement.
- The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Finished joints are checked and backed by our 12-month guarantee.

Advice
Surface 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 flagging broken arrises before sealing.
Brickwork and blockwork joints
A brick movement joint full of old mortar or debris can’t close. Everything is raked out before backing and sealant go in.
Owners, agents and contractors
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Hempstead. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Why it’s worth doing now in Hempstead
Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now, as damage continues meanwhile. Urgent joints now, the rest later, is often the sensible plan. Around Hempstead, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

What we are called out for in Hempstead
On trafficked joints, wheels and salts do the damage. Tyres and wheels press on the edges and the sealant, while de-icing salts and grit attack the seal. The product has to be suited to the traffic.
Look out for the following:
- Hardened, cracked sealant on exposed facades
- Arrises breaking up along floor joints
- Water dripping through deck or ramp joints
- Sealant pulling off the joint face
In and around Hempstead, the right filler or sealant for each joint depends on the traffic and the movement it takes.
What your quote should include
- What site paperwork they can supply
- Which product they’ll use, and why it suits the joint
- How long is the guarantee, and what does it include?
- How the joint faces will be prepared and primed
