Farnham: questions and answers
Will you take on work at estates like Hookstile Trading Estate, close to Farnham?
Yes. Estates, retail parks and business parks around Farnham, Hookstile Trading Estate among them, are all within reach. A few photographs and the unit address let us price the work.
Do we have to stop operations in Farnham while the joints are sealed?
Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we’ll plan from there.
How much does the work cost?
We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
Is movement joint sealing guaranteed?
A 12-month guarantee covers our workmanship, and we’re fully insured for public liability. Keeping joints clear of debris helps them last.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.
What exactly is a movement joint?
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 way they’re sealed is similar.
Expansion joint sealing for commercial buildings in Farnham
Mastic Doctor has sealed movement joints since 2005 for contractors, facilities managers and 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. Most enquiries involve arrises breaking up along floor joints and damp inside where a wall movement joint has failed, across car park decks and ramps, cladding panel joints and blockwork control joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Farnham, preparation and product choice get the time they need.
Towns such as Farnham usually have an industrial estate or a few business units, with warehouse floors and loading areas. Small units are often busy, so joints are done at times that suit the occupier.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

For managing agents and facilities managers
As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
When to call us in Farnham
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 often shows on rushed work.
These are often picked up first by site or facilities staff:
- Water getting into the wall through a failed joint
- Leaks through car park deck joints onto the level below
- Brittle, chalky sealant on external joints
- Sealant pulling off the joint face
A campus such as University for the Creative Arts (0.6 miles north-west of Farnham) has long runs of movement joint in its buildings, decks and paving.
What to look for in a quote
- Is the sealant right for the movement and the substrate?
- Their plan for phasing and protecting the area
- What level of public liability insurance do they hold?
- Will CSCS-carded applicators be on site?
What happens if it’s left?
Some quotes just add sealant over the old bead. A bead laid on top of the failed one neither grips nor flexes properly. Full removal and preparation is in every quote. For businesses and landlords in Farnham, a tidy, sound joint also matters for appearance. Fresh sealant makes a building look maintained.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

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. Town-centre premises in Farnham may have limited parking, so tell us what’s nearby. On estates and business parks it’s typically simpler.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Preparing the site
- Let us know about inductions and permits
- Confirm the product named in the specification
- Make sure the joints can be reached

Podium joints
On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix.
Cladding panel joints
We confirm what access is in place before pricing. Close-up photos help us judge the joints, or we visit if they don’t show enough.
Traffic, movement and joints around Farnham
Central London is about 36 miles from Farnham. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift. Rainfall across the South East, Farnham included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.
Estates like Hookstile Trading Estate (to the south-west of Farnham) combine warehouse slabs, yards and loading bays, all with joints under wheels. For a centre such as Farnham Retail Park, 0.8 miles north-east of Farnham, the service yard and car park joints typically need attention first.

Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Treat a small split as a warning, not a cosmetic issue
- Keep racking legs and heavy point loads off floor joints
- Put movement joints on the planned maintenance inspection round
- Leave barriers in place until fresh joint sealant has cured
On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal.
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.
