Common questions from Writtle clients
Can you take on a job at a hospital such as Chelmsford and Essex Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Writtle too small for you to travel to?
No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
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.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Expansion joint sealing in Writtle
Mastic Doctor has sealed movement joints since 2005 for contractors, facilities managers and owners. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. If you’re dealing with torn sealant in brick or block movement joints and expansion joints filled with dirt and stones, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Writtle tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Around Writtle, most floor and movement joint jobs are single buildings or yards, so we gather photographs and measurements first. Getting widths, depths and traffic details up front means one visit, not two.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

For managing agents and facilities managers
CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Why deal with it now?
Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open without shutting the whole car park. Tell us what has to stay open and we’ll plan around it. In a smaller place such as Writtle, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
What you get with us
- Joints cleaned back to sound surfaces
- A fixed quote before work starts
- A Constructionline member, so easy to vet
- Matching to RAL references, product permitting

From enquiry to sign-off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a site in Writtle, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.
- 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.
- 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
- Let building users know which areas are affected
- Agree which areas must stay open
- Have the specification and drawings to hand

What we are called out for in Writtle
Car park decks and floors face loads that walls never see. Wheel loads stress the sealant and the arrises, while grit and salts work into any gap. The product has to be suited to the traffic.
It’s worth sending us details if you spot any of the following:
- Brittle, chalky sealant on external joints
- Car park joints leaking onto vehicles below
- Arrises breaking up along floor joints
- Expansion joints filled with dirt and stones
Warehouse floors on estates like Widford Industrial Estate, 1.2 miles east of Writtle, carry pallet trucks and forklifts over every saw-cut joint.
Before you book anyone
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How they’ll work around occupants
- Is the sealant right for the movement and the substrate?
- Whether primer will be used where the manufacturer specifies it
How the job changes by surface
Joints between different materials
Different materials meeting at a joint rarely move in step. The product must bond to both substrates and cope with the movement, with primer where specified.
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, phased so parts of the car park stay open.
Quoting for work in Writtle
To price the job, we consider:
- The total length or number of joints
- Backing rod, priming and other preparation
- Any access equipment needed
- Which sealant the job calls for
A quote for movement joints depends on quantities, condition and access, plus any specification you are working to. Ask us for a fixed quote.

- The product your specification calls for
- When you need the work done
- Whether an asbestos survey exists
- Anything awkward about access or site hours
