Dumpford: questions and answers
Is Dumpford too small for you to travel to?
Not at all. Dumpford is within our area. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Is a hospital such as Midhurst Community Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also give us a call on 01277 525 020 or email a schedule or drawings. Include photographs or drawings if you have them.
What if the joint edges are damaged?
Spalled edges need repairing before a new seal will last and we will flag every length affected. A bead on a broken edge soon lets go.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Expansion joint sealing in Dumpford, done properly
For movement joints in Dumpford, photos and approximate lengths are the best start. We’ll come and look where photos don’t show enough. You can also phone 01277 525 020 or email us to talk the joints through. The enquiries we see most involve previous reseals laid over old sealant and car park joints leaking onto vehicles below, on car park decks and ramps, brickwork movement joints and podiums and floor movement joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Dumpford, preparation and product choice get the time they need.
In and around smaller places like Dumpford, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
Work we carry out in West Sussex comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or email the details over and we’ll come back to it.

Cost factors for movement joints
Before we quote, we look at:
- How accessible the joints are
- Specialist products, such as fire-rated or hygienic sealants
- Whether the work must be split into stages
- The site’s rules and procedures
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What to include in your enquiry
We can often quote from photos and a few details. Please tell us:
- The site address and postcode
- Photos of the joints, close up and from further back
- The asbestos register, for older buildings
- 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 photographs and a few notes.
Keeping the joints sound
To get the most from the new sealant:
- Reopen bays and walkways only after the stated cure time
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Report split or peeling joint sealant early
- Avoid parking heavy plant or pallets on joint lines
Debris does more harm to joint sealant than most people realise. Stones pressed into the bead by wheels or feet can puncture it and decks and floors suffer most. A routine sweep is the simplest protection.
Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one so you can prioritise and budget. We can suggest an order, worst joints first.
Slabs, ramps and loading bays in Dumpford
Dumpford sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints.

Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift.

Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
When to call us in Dumpford
When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes, and it’s common on joints sealed in a hurry.
Clients normally get in touch after noticing one or more of the following:
- Leaks through car park deck joints onto the level below
- Arrises breaking up along floor joints
- Torn sealant in brick or block movement joints
- Sealant pulling off the joint face
Sites like Midhurst Community Hospital, 3.6 miles to the east of Dumpford, carry ambulances, deliveries and visitors’ cars over their road and deck joints.
What your quote should include
- Their plan for phasing and protecting the area
- What the guarantee covers, and for how long
- How they handle RAMS and site documents
- How the joint faces will be prepared and primed
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.
Podium joints
On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix.
From enquiry to 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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Dumpford, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.
- We assess the joints on site or from photos, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- 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.
- 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.
Preparing the site
- Flag any permit to work we will need
- Share your working hours and any access restrictions
- Send asbestos survey details if the building is pre-2000
