How the job changes by surface
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler and a flexible sealant where the joint moves more.
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. We prepare the faces thoroughly and prime where the maker calls for it, so the new seal holds.
Expansion joint sealing in Grafham
A movement joint only works while its seal does. Once it fails, water, grit and debris get in, 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. If you have chipped joint edges on forklift routes and debris jammed in movement joints, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Grafham, that means joint design, primers and backing rod as standard.
For a site near Grafham, measurements and photographs up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Traffic, movement and joints around Grafham
Grafham sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, while winter salting gets into any joint left open. Grafham is about 30 miles from central London. Warehousing clusters around the motorways that ring and radiate from London.
For an estate such as Milford Hospital, 3.7 miles to the west of Grafham, the joints in ramps, decks and long building elevations all need attention over time. At places like Littlemead Industrial Estate, 2.3 miles south-east of Grafham, joints are sealed a section at a time so operations carry on. Estates like Manfield Park Industrial Estate, 1.9 miles to the south-east of Grafham, combine warehouse slabs, yards and loading bays, all with joints under wheels.
Grafham is about 6 miles south of Guildford, in Surrey. We cover commercial sites throughout Grafham, for single jobs and planned programmes alike. 379 places across Surrey fall within our area, Grafham among them. Our Reading page has more on work in that area, about 27 miles away.
Work on movement joints is covered throughout GU5. If your building is just outside Grafham, we cover Birtley Green (1 mile north), Shamley Green (1 mile north), Thorncombe Street (1 mile west), Stroud Common (1 mile north-east) and Rowly (2 miles east). A short drive away, we cover Guildford (6 miles north), Woking (11 miles north), Camberley (14 miles north-west), Farnham (11 miles west), Reigate (15 miles east) and Dorking (10 miles north-east).
Around Grafham
We work on buildings around Cucknell's Wood, among other places. The nearest railway station is Chilworth station, roughly 3.5 miles north. Other landmarks nearby include Godalming Museum (3.6 miles north-west) and Guildford Castle (4.9 miles north). Not far away are St Martha's Hill and Colyer's Hanger and Lower Lake.
Why deal with it now?
On a car park, resealing joints in phases keeps the deck open. Phased work by bay or zone lets the rest stay in use. Tell us what has to stay open and we’ll plan around it. Halls, stores and units around places like Grafham may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Are you CHAS accredited and on Constructionline?

Are your applicators CSCS-carded?

Do you use silicone or polyurethane in movement joints?
The right product depends on the joint. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints unless the specification names something else.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Building owners, agents and FMs in Grafham
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
On site: what to expect
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. Rural sites near Grafham may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- We look at the joints, their width and how they’ve failed.
- Next, we fix a price and confirm the sealant we propose for the movement.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Getting the site ready
- Tell us your opening times and when work is allowed
- Make sure the joints can be reached

Advice
When it isn’t the sealant
We check first that sealant really is the fix. It won’t put right:
- Joints too narrow for the movement, which need redesigning by the engineer
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
If in doubt, give us a call on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

What else we do in Grafham
Site staff or a sealant specialist?
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
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.
