Expansion joint sealing for commercial buildings in Fair Oak
Mastic Doctor has sealed movement joints since 2005 for contractors, facilities managers and 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. Site teams most often ask us about previous reseals laid over old sealant and hardened, cracked sealant on exposed facades, across cladding panel joints, podiums and floor movement joints and brickwork movement joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Fair Oak, preparation and product choice get the time they need.
Rural business units around smaller places such as Fair Oak often have new slabs laid inside older buildings. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Joints that move: notes for Fair Oak
Fair Oak is about 64 miles from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift. Fair Oak sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, while winter salting gets into any joint left open.
Retail centres such as Bradbeers Retail park (to the south of Fair Oak) have floors, service yards and car parks with joints under constant traffic. Phasing is what makes joint work possible on busy sites such as Vicarage Farm Business Park (1 mile north of Fair Oak): one bay, aisle or car park row at a time.
Fair Oak is about 2 miles east of Eastleigh, in Hampshire. Any commercial site in Fair Oak is covered, for single jobs and planned programmes alike. We work across 723 places in Hampshire.

Diagnose, treat, sign off
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. For a site in Fair Oak, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Preparing the site
- Let us know about inductions and permits
- Clear stock, furniture or equipment away from the joints
- Point out any areas we must not close

Different surfaces, different methods
Brickwork and blockwork joints
Long brick and block elevations have movement joints at intervals. We use a sealant rated for the movement, usually low-modulus.
Podium joints
Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal.

Common problems we fix in Fair Oak
Sealant peeling cleanly off one side is an adhesion failure. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons, and it’s common on joints sealed in a hurry.
It’s worth sending us details if you spot any of the following:
- Brittle, chalky sealant on external joints
- New sealant over old, now failing
- Car park joints leaking onto vehicles below
- Debris jammed in movement joints
For a school such as Fair Oak Junior School, playground and building joints can be done in the holidays.
Questions to ask before you book
- Will RAMS and insurance details be available?
- Is the sealant right for the movement and the substrate?
- Their pre-qualification and accreditations
- How joint depth will be controlled
Questions we are asked in Fair Oak
Is Fair Oak off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Does your area include sites such as Deer Park Farm Industrial Estate, near Fair Oak?
Yes, sites like Deer Park Farm Industrial Estate are within our area, along with the rest of Fair Oak. A few photographs and the unit address let us price the work.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
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.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Work for main contractors and building owners
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Fair Oak can form part of a wider programme.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Should maintenance staff do it?
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
After the work
Regular inspection catches problems early. Specifically:
- Keep product details with the building records for the next reseal
- Report split or peeling joint sealant early
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Plan racking layouts so feet don’t land on a joint
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, call 01277 525 020 or email a schedule or drawings with photographs.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster, and the damage spreads along the joint. Keeping the filler or sealant sound protects the floor.
