About our mastic sealing in Potters Bar
Across Potters Bar and the rest of Hertfordshire, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote or we can visit. If you have patchy repairs in mismatched sealant and damp patches beside frames, we can put it right, on window and door perimeters on blocks, shopfronts below residential blocks and communal kitchens and washrooms alike. Whoever orders the work in Potters Bar, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Older buildings in towns like Potters Bar have often had replacement windows fitted at different times, so mastic around them can be of mixed age and quality. Looking at the whole building first shows what needs doing now and what can wait.
A 12-month guarantee applies to all our work in Hertfordshire. If an installation problem shows up, phone 01277 525 020 or send details through our quote form and we will arrange a return visit.

FAQs: Potters Bar
Can you work at a site such as Hollies Way Industrial Park, by Potters Bar?
Yes. Estates, retail parks and business parks around Potters Bar, Hollies Way Industrial Park among them, are all within reach. To start, just speak to us on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Can one quote cover a number of our buildings near Potters Bar?
Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Do you work for managing agents and housing associations?
Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn so you can plan around it.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
Do you guarantee the mastic work?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the building height and any access already in place, and we will tell you how we’d approach it.
What sealant work can’t fix
Being straight saves everyone time. Fresh joints won’t solve:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Materials that need asbestos testing before work
- Misted or failed double-glazed units
Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

On site: what to expect
On arrival, we report to your site contact and complete whatever induction the building runs.

At about 14 miles from central London, Potters Bar is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.
Student blocks close to universities like University of Hertfordshire, 4.5 miles to the north of Potters Bar, are easiest to work on between tenancies. If you own or manage units on a site such as Hollies Way Industrial Park, less than half a mile east of Potters Bar, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Should maintenance staff do it?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Keeping the joints sound
Regular inspection catches problems early. Specifically:
- Avoid piecemeal callouts where you can
- List the paperwork your organisation requires when you send details
- Have the asbestos survey to hand for older buildings
- Look at the sunniest and most exposed elevations first
Keep records of when each building was resealed. It helps plan the next round and shows what was done.
Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first and the job grows.
What affects the price in Potters Bar
We price every job individually. The things that drive the figure:
- Location, for remote and island sites
- Whether old sealant has to be cut out first
- Any access equipment needed
- The total length or number of joints
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
Before you send an enquiry
A good diagnosis starts with the right details. Tell us:
- What the building is and how it’s used
- Your programme or deadline
- A wide shot and a close-up of the area
- Any specification or named product
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.
