About our expansion joint sealing in Moulsford
Mastic Doctor has sealed movement joints since 2005, for main contractors, FMs, managing agents and building owners. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. We work on blockwork control joints, car park decks and ramps and precast concrete panel joints, and the usual reasons a site gets in touch are arrises breaking up along floor joints and expansion joints split through the centre of the bead. A specialist sealant contractor works differently from a general builder: in Moulsford, that means joint design, primers and backing rod as standard.
In and around smaller places like Moulsford, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Moulsford: questions and answers
Does a site in Moulsford have to shut while its joints are sealed?
In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we’ll plan from there.
Is Moulsford too small for you to travel to?
Not at all. Moulsford is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
When can you be on site?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Can the sealant be colour-matched?
That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Can a joint be sealed if the edges are broken?
A bond is only as strong as the material behind it, so broken or crumbling edges have to be repaired first. Where it’s visible beforehand, we will say so when we quote.
Keeping the joints sound
To get the most from the new sealant:
- Inspect movement joints alongside other routine building checks
- Leave barriers in place until fresh joint sealant has cured
- Keep scrapers and ploughs from dragging across joint sealant
- Keep stones and debris out of open joint lines
Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in. If anything looks wrong, phone 01277 525 020 or send photos by email with photographs.
On a multi-storey car park, a failed joint normally shows up as a leak onto the deck underneath. That water often carries de-icing salts with it, which is bad news for the concrete and the people parking below. Sealing the joint promptly stops it at source.

When to call us in Moulsford
With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Sealant fixed to the base and sides can’t flex, so it tears.
Common reasons buildings call us in:
- Hardened, cracked sealant on exposed facades
- Arrises breaking up along floor joints
- Sealant peeling off one face of the joint
- Rain penetration at brick or block movement joints
In a school such as Cranford House School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
What to look for in a quote
- Is the sealant right for the movement and the substrate?
- Whether primer will be used where the manufacturer specifies it
- How joint depth will be controlled
- What the guarantee covers, and for how long
Leave it or put it right?
On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open, compared with a full closure. We agree phasing with you before work starts. For buildings around smaller places like Moulsford, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

Joints that move: notes for Moulsford
At about 46 miles from central London, Moulsford is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. Moulsford is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open.
Around Moulsford, each joint gets a filler or sealant matched to what crosses it and how much it moves.

Our process
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around Moulsford, tell us how to find it and who will meet us. 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.
- A fixed quote names the sealant we propose and its movement class.
- 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.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Preparing the site
- Clear stock, furniture or equipment away from the joints
- Explain the parking and delivery arrangements
- Send asbestos survey details if the building is pre-2000

What sets the cost
Your fixed quote is built from the real scope. It allows for:
- How much existing material needs removing
- Whether the work must be split into stages
- Any access equipment needed
- Site requirements such as inductions and permits
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.
Before you send an enquiry
To price the job accurately, we need a clear picture of the site. Send us:
- Any dates the work must fit around
- A wide shot and a close-up of the area
- The asbestos register, for older buildings
- Drawings or a marked-up plan, if available
The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or call 01277 525 020 or email a schedule or drawings to discuss it first.
Surface by surface
Cladding panel joints
Metal and composite panels shift considerably as temperatures change. A sealant with the right movement class is chosen in a colour confirmed for that product.
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.
