Expansion joint sealing in Lindfield, done properly
Mastic Doctor has sealed movement joints since 2005, for main contractors, FMs, managing agents and building owners. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. We work on car park decks and ramps, podiums and floor movement joints and precast concrete panel joints, and what we are called in for most is previous reseals laid over old sealant and spalled or broken joint edges in floors and decks. Facilities teams, main contractors and managing agents in Lindfield tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Work in a smaller place like Lindfield is typically one building at a time, so we gather photos and measurements first. That way the right materials come on the day and the job is done in one visit where possible.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

FAQs: Lindfield
Is Lindfield too small for you to travel to?
Not at all. Lindfield is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Can you take on a job at a hospital such as Princess Royal Hospital?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Do you use silicone or polyurethane in movement joints?
We choose a sealant with a movement capability that suits the joint as set out in BS EN ISO 11600. Hybrid or MS polymer products suit some mixed-material joints.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Are expansion joints and movement joints the same thing?
Movement joint is the broad term for any joint built in to let a structure move. On site, people tend to use them interchangeably, and the sealing method is much the same.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
What the job involves on each surface
Joints between different materials
Junctions between brick and render, or concrete and cladding, move independently. We choose a sealant that grips both faces, with primer where specified.
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.
What affects the price in Lindfield
These are the things that shape the price:
- How much there is to seal
- Specialist products, such as fire-rated or hygienic sealants
- Joint width, depth and condition
- Distance, for remote addresses
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Details that help us quote
Whether it’s one area or a whole building, the same details help:
- How the joints are reached, and at what height
- Asbestos survey details if the building is older
- When you need the work done
- Specification clauses that apply
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
General trades versus a specialist
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
When to call us in Lindfield
Some joints were never sealed with the right product. Products not classed for the movement fail early. BS EN ISO 11600 classifies building sealants by movement capability, and specifications often refer to it.
Look out for the following:
- Movement joints with split or torn sealant
- Layers of sealant in a movement joint
- Arrises breaking up along floor joints
- Car park joints leaking onto vehicles below
Large sites such as Princess Royal Hospital, 1.6 miles south of Lindfield, have car parks, service roads and long elevations with movement joints in brick and panels.

- How joint depth will be controlled
Honest limits
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Joints too narrow for the movement, which need redesigning by the engineer
- Leaks coming from the membrane rather than the joint seal
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
If you’re not sure, just call the office on 01277 525 020 or email the details over and we will give you a straight answer before you book.
Joints and surfaces we work on

Diagnose, treat, sign off
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. Several jobs near Lindfield can be grouped on one trip. Tell us your site hours and we will plan around them.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Preparing the site
- Share the asbestos register for older buildings
- Tell us which areas need to stay in use
- Confirm the product named in the specification

Expansion joint sealing in Lindfield: the local picture
Lindfield sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints. Central London is about 34 miles from Lindfield. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital.
Office parks like More House Farm Business Centre (2.9 miles south of Lindfield) have decks, ramps and clad elevations whose joints take movement every day. In a school such as Lindfield Primary Academy, movement joints in brick, block and hall floors tend to be forgotten until they leak.
