Mastic sealing across Hartley Mauditt
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Hartley Mauditt are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- Each block or building is walked and the failed joints recorded with the likely cause.
- A fixed quote follows, split by block or building if that suits you.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Before we start on site

Advice
About our mastic sealing in Hartley Mauditt
On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Communal entrances and stairs stay usable throughout. We work on communal entrances and stairwells, external wall and movement joints and balcony and threshold joints, and what we are called in for most is draughts at frames across a block and repeated reactive repairs to the same buildings. A specialist sealant contractor works differently from a general builder: on jobs in Hartley Mauditt, preparation and product choice get the time they need.
Around smaller places like Hartley Mauditt, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Planned mastic for Hartley Mauditt portfolios
At about 45 miles from central London, Hartley Mauditt is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.
For agents with blocks near Alton station (2.5 miles north-west of Hartley Mauditt), a block-wide mastic programme deals with frames, balconies and entrances in one go. Older community buildings, St Leonard's Church among them, often have frames of mixed ages whose mastic varies. Landlords with units on estates such as Southlands Industrial Park, 2 miles to the south-east of Hartley Mauditt, can bring frame, door and external mastic across several units into one programme.
Hartley Mauditt is about 3 miles south-east of Alton, in Hampshire. Across the GU34 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 723 places in Hampshire, large and small. For work in that direction, see our Portsmouth page.
Anyone looking for mastic sealing in GU34 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. Just outside Hartley Mauditt, we also work in East Worldham (1 mile north), Oakhanger (2 miles east), Upper Farringdon (2 miles west), Farringdon (2 miles west) and Chawton (2 miles north-west).

Landmarks near Hartley Mauditt
The nearest railway station is Alton station, roughly 2.5 miles north-west of the centre. A little further out are Alton Community Hospital (2.5 miles north-west) and The Romany Museum (1.6 miles south). For a walk, there’s Selborne Hill and Deadwater Valley.
After the work
For the best life from the joints:
- Check the asbestos register before any old mastic is disturbed
- Group repairs into a planned programme
- Make mastic part of routine maintenance checks
- Look at the sunniest and most exposed elevations first
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
One failed perimeter usually means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
What the job involves on each surface
Communal areas
Joints at low level in communal areas take knocks from bins, bikes and buggies and tend to fail first.
Estate-wide resealing programmes
Consistent products and colours across an estate make future maintenance simpler and easier to manage.
What happens if it’s left?
Adding sealant to cyclical maintenance is an easy win. Leaving it until there’s a leak turns it into reactive work and less choice about when. One visit to deal with every failing joint makes more sense than several trips to a place like Hartley Mauditt, rather than one at a time. Send photos of each area and we will quote for the lot.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
