For owners and agents in Chipping
The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. Chipping is about 32 miles from central London. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate.
Site managers at schools like Freman College can fit frame mastic into the summer works.

How we handle mastic sealing in Chipping
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. If you have patchy repairs in mismatched sealant and estate-wide sealant that is simply worn out, we can put it right, on external wall and movement joints, communal kitchens and washrooms and communal entrances and stairwells alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Chipping it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Owners and agents with buildings around smaller places such as Chipping 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.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Why act early in Chipping
Failed perimeter mastic lets cold air in around frames, and they often blame the windows. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Older rural buildings around Chipping move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

Common problems we fix in Chipping
Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks, especially on south and west faces.
Look out for the following:
- Open joints in brickwork or panels
- Old repairs sealed over failed mastic
- Communal area joints that look neglected
- Complaints coming in block by block
Property owners at sites such as Park Farm Industrial Estate, 1.1 miles to the south of Chipping, can have mastic renewed between lettings.

What the job involves on each surface
Window and door perimeters on blocks
Frames vary from uPVC to aluminium and timber, so the grade we pick has to bond to frame and wall alike. Colours are confirmed for the product used.
Commercial and mixed-use buildings
Commercial buildings have mastic at shopfronts, entrances and external joints. We work across portfolios on a planned basis.
Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes one or more days per building, depending on the joint lengths and the access, and our waste is bagged and taken away as we go. For work around Chipping, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
What we need from you
- Arrange parking or a loading space
- Move anything stored against the joints
- Send any specification or drawings in advance
Getting a fixed quote
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

For managing agents and facilities managers
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
After the work
Your facilities or cleaning team can help the joints last. Share these points with them:
- Prioritise elevations facing the weather
- Keep bins and bikes away from communal door frames
- Share the asbestos register when you send details
- Make mastic part of routine maintenance checks
Log the date and extent of the resealing for each block. It helps plan the next round and shows what was done.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.

Will you take on work at estates like Park Farm Industrial Estate, close to Chipping?

Is Chipping too far out for you?
No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you plan resealing across several buildings?
Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.
Do you work for managing agents and housing associations?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
