Expansion joint sealing for commercial buildings in Tadworth
A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water, the joint can’t close properly and its edges begin to crumble. Resealing at the first signs of failure is far cheaper than repairing the material either side. We work on precast concrete panel joints, cladding panel joints and podiums and floor movement joints, and what we are called in for most is hardened, cracked sealant on exposed facades and movement joints with split or torn sealant. Searching for sealant specialists in Tadworth? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Around Tadworth, most floor and movement joint jobs are single buildings or yards, so we gather photographs and measurements first. That way the right materials come on the day and the job is done in one visit where possible.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Warehouse floors and decks around Tadworth
Tadworth is about 15 miles from central London. Warehousing clusters around the motorways that ring and radiate from London. Rainfall across the South East, Tadworth included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints.
Large sites such as Epsom General Hospital, 2.6 miles to the north-west of Tadworth, have car parks, service roads and long elevations with movement joints in brick and panels. In a school such as Tadworth Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
Tadworth is about 3 miles south-east of Epsom, in Surrey. Across the KT20 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across Surrey, 379 places are covered, including Tadworth. Sites around London have their own page, roughly 15 miles from Tadworth.

What we can’t put right
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Changing the joint layout or spacing of a structure
- Leaks coming from the membrane rather than the joint seal
- Movement on a scale no sealant is meant to absorb
If you’re not sure, just give us a call on 01277 525 020 or email drawings and photos and we’ll give you a straight answer.
Joints and surfaces we work on
- Blockwork control joints
- Car park decks and ramps

- Brickwork movement joints
- Podiums and floor movement joints
- Precast concrete panel joints
Our process
Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. If neighbouring businesses or buildings around Tadworth need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.
- First, the joints are inspected for width, movement and the type of failure.
- You get a fixed quote with the product and its movement capability stated.
- The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Finished joints are checked and backed by our 12-month guarantee.
What we need from you
- Share the asbestos register for older buildings
- Have the specification and drawings to hand
- Tell us what induction or permit system the site runs

How the quote is worked out
Quotes vary with the job. It mainly depends on:
- Backing rod, priming and other preparation
- How much there is to seal
- Working within restricted access windows
- Specialist products, such as fire-rated or hygienic sealants
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
What we need to price the job
Whether it’s one area or a whole building, the same details help:
- Access details, including height
- Whether an asbestos survey exists
- Rough lengths or quantities, or drawings if you have them
- What the building is and how it’s used
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, phone 01277 525 020 or email the details over.
When to call us in Tadworth
Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600, and specifications often refer to it.
Common reasons buildings call us in:
- Arrises breaking up along floor joints
- Torn sealant in brick or block movement joints
- Hardened, cracked sealant on exposed facades
- Sealant peeling off one face of the joint
Campuses like University for the Creative Arts - Epsom, 2.6 miles north-west of Tadworth, mix old and new buildings, with movement joints wherever they meet.
Questions to ask before you book
- Will RAMS and insurance details be available?
- What level of public liability insurance do they hold?
- How long is the guarantee, and what does it include?
- Whether their applicators hold CSCS cards
Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
FAQs: Tadworth
Is Tadworth off your patch?
Not at all. Tadworth is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you take on a job at a hospital such as Epsom General Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What if the joint edges are damaged?
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.
Are you CHAS accredited and on Constructionline?
Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.
What timescale should we allow for resealing expansion joints?
That depends on joint lengths, widths, access and how much old sealant or filler needs removing. As a guide, it normally takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing.
How do I request a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.

What the job involves on each surface
Car park decks and ramps
Deck and ramp joints take tyre loads, grit and de-icing salts. We use a sealant made for wheel loads and the expected movement, phased so parts of the car park stay open.
Internal floor movement joints
Forklift and pallet-truck wheels break unsupported joint edges. We match the product to the traffic and the movement.
