About our mastic sealing in Long Ditton
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 along with complaints. If you have communal area joints that look neglected and occupiers reporting cold air round windows, we can put it right, whatever the surface. A single leaking joint is often how a building in Long Ditton first comes to us: we look at the rest while we’re there and tell you what we find.
In a smaller place such as Long Ditton, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. The mastic around their frames and external joints ages like anywhere else.
A 12-month guarantee applies to all our work. Should something we installed fail, call the office on 01277 525 020 or send details through our quote form and we’ll come back to it.

Local landmarks in Long Ditton

After the work
Regular inspection catches problems early. Specifically:
- Keep a record of when each building was resealed
- Have the asbestos survey to hand for older buildings
- Keep bins and bikes away from communal door frames
- Prioritise elevations facing the weather
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.
Your questions answered
Do you work for managing agents with blocks near Surbiton station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.
Is Long Ditton too far out for you?
Not at all. Long Ditton is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
Can weather delay the job?
Outside, 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. Internal work is rarely affected.
Can you seal joints high up on a block?
Every block is different. We agree access with you at quote stage so there are no surprises.
Can you reseal a whole block or estate?
Block-wide and estate programmes are common. The quote can be split however suits your budgeting.
Do you guarantee the mastic work?
Our workmanship carries a 12-month guarantee and we hold public liability insurance.
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.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

How the quote is worked out
We price every job individually. The main factors are:
- Joint width, depth and condition
- The total length or number of joints
- How much existing material needs removing
- Phasing around occupants
A quote for mastic joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.
Before you send an enquiry
We can often quote from photographs and a few details. It helps to include:
- Any dates the work must fit around
- The asbestos register, for older buildings
- What the building is and how it’s used
- How the joints are reached, and at what height
To get a fixed quote, phone 01277 525 020 or email drawings and photos. Our quote form is another easy route.
Common problems we fix in Long Ditton
Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant, so these repairs rarely last.
Look out for the following:
- Damp patches beside frames
- Cracked, hardened mastic round windows on a block
- Mastic failing across several blocks on an estate
- Draughts at frames across a block
Landlords with units on estates such as Fairfield Trade Park, 1.7 miles north-east of Long Ditton, can bring frame, door and external mastic across several units into one programme.
What your quote should include
- Whether their applicators hold CSCS cards
- How the existing material will be dealt with
- What the guarantee covers, and for how long
- Whether primer will be used where the manufacturer specifies it

What happens if it’s left?
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once, under a single quote and a single programme. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
