About our mastic sealing in Pottersheath
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed, with backing rod setting the depth where it’s needed. We work on balcony and threshold joints, external wall and movement joints and window and door perimeters on blocks, and the failures we are asked to look at most are open joints in brickwork or panels and complaints coming in block by block. One point of contact handles commercial sealant work in Pottersheath from the first photos to the final walk-round, whether it’s one building or several.
For buildings around smaller places like Pottersheath, we group work so one trip covers it. Send photos of the frames and joints and we’ll give a fixed quote.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Doing it in-house
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Mastic sealing in Pottersheath: the local picture
Pottersheath is about 25 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide. Pottersheath sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.
Older community buildings, Church of St Michael and All Angels among them, often have frames of mixed ages whose mastic varies. For agents with blocks near Knebworth station, 1.3 miles to the north-east of Pottersheath, a block-wide mastic programme deals with frames, balconies and entrances in one go.

- The site’s rules and procedures
- How much existing material needs removing
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
Before you send an enquiry
We can often quote from photos and a few details. It helps to include:
- How the joints are reached, and at what height
- Clear photographs of the problem areas
- The postcode of the building
- What the building is and how it’s used
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

What else we do in Pottersheath
Do you need mastic sealing in Pottersheath?
Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits long before it should.
Common reasons buildings call us in:
- Movement joints with sealant missing
- Patchy repairs in mismatched sealant
- Cracked, hardened mastic round windows on a block
- Draught complaints from residents or tenants
Landlords with units on estates such as Arlington Business Park, 2.7 miles to the north of Pottersheath, can bring frame, door and external mastic across several units into one programme.
Before you book anyone
- What site paperwork they can supply
- Do they follow the manufacturer’s priming guidance?
- How long is the guarantee, and what does it include?
- Will CSCS-carded applicators be on site?
Maintenance after handover
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Include mastic in your cyclical inspections
- Plan resealing building by building rather than complaint by complaint
- Have the asbestos survey to hand for older buildings
- Reduce knocks to communal area joints
Add mastic joints to your cyclical inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first and the job grows.
Common questions from Pottersheath clients
Is Pottersheath too small for you to travel to?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Will you take on work at estates like Arlington Business Park, close to Pottersheath?
Yes. We cover Pottersheath and the area around it, including industrial estates, business parks and retail parks such as Arlington Business Park. Send details of the unit and the work through our quote form for a quick quote.
How many days will you need on site?
That varies with the scale of the job, though a typical visit normally takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we will set out a timescale with the quote.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
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.
Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Our process
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off.

- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- The joints are prepared and resealed with the right product.
- Buildings are completed in turn.
Before we start on site
- For older buildings, check the asbestos register before work
- Explain the parking and delivery arrangements
- Have the specification and drawings to hand
