FAQs: Little Wittenham
Do you work for managing agents with blocks near Appleford station?
Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Is Little Wittenham too small for you to travel to?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Can people stay in the building while you reseal?
The work is planned around occupiers. We agree the programme so you can notify occupiers and communal access is kept open.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
How we handle mastic sealing in Little Wittenham
Owners and agents usually inherit a building’s mastic rather than choose it, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. Site teams most often ask us about mastic failing across several blocks on an estate and draught complaints from residents or tenants, on communal entrances and stairwells, shopfronts below residential blocks and window and door perimeters on blocks. For commercial sealant work in Little Wittenham, you deal with one contact from quote to sign-off, whether it’s one building or several.
Owners and agents with buildings around smaller places such as Little Wittenham tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Should maintenance staff do it?
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.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
On site: what to expect
Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. If others near Little Wittenham need work, visits can be combined. You will have a fixed quote before work starts.
- Each block or building is walked and the failed joints recorded with the likely cause.
- You get a fixed quote, priced per building where that helps your budgeting.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- We remove the old mastic completely and clean the joint faces back.

Why deal with it now?
Piecemeal repairs over the years often leave mismatched sealant. A block-wide reseal gives one product, one colour and one guarantee. Converted and older buildings near places like Little Wittenham tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
