Questions about Ayot Green
Is Ayot Green off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Does your area include sites such as Little Ridge Industrial Estate, near Ayot Green?
Yes. Our area takes in Ayot Green and its surroundings, with estates and business parks such as Little Ridge Industrial Estate included. A few photographs and the unit address let us price the work.
Can you take on resealing for a block portfolio?
Yes, that’s exactly who this service is for. We work through buildings in a planned order so you can plan around it.
Can you seal joints high up on a block?
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.
Do you check for asbestos in old sealant?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
Will residents or tenants be disturbed?
Residents and tenants carry on as normal. If any flats or units need access, we’ll tell you in advance so it can be arranged.
What will the job cost?
We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.
About our mastic sealing in Ayot Green
Owners and agents usually inherit a building’s mastic rather than choose it, and it ages quietly: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. Most enquiries involve repeated reactive repairs to the same buildings and damaged joints in communal entrances and corridors, across window and door perimeters on blocks, communal kitchens and washrooms and communal entrances and stairwells. Looking for mastic applicators who cover Ayot Green? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Owners and agents with buildings around smaller places such as Ayot Green tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Check the asbestos register before any old mastic is disturbed
- Check sealant joints during planned building inspections
- Log resealing dates block by block
- Plan resealing building by building rather than complaint by complaint
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.
How the quote is worked out
To price the job, we consider:
- Distance, for remote addresses
- Site requirements such as inductions and permits
- Access and working height
- Whether old sealant has to be cut out first
A quote for mastic joints depends on quantities, condition and access. Call for a quote.
Before you send an enquiry
Good information means a firmer quote. Helpful details to send:
- Any dates the work must fit around
- Anything awkward about access or site hours
- Approximate linear metres or a joint schedule
- Asbestos survey details if the building is older

Blocks and managed buildings in Ayot Green
Ayot Green is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. There are two care or nursing homes within about 2 miles of Ayot Green. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings.
Churches, halls and community buildings such as Church of St Peter are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Owners of student blocks near University of Hertfordshire, 4.2 miles to the south of Ayot Green, can schedule frame and external mastic for the summer vacation. Landlords with units on estates such as Little Ridge Industrial Estate (to the south-east of Ayot Green) can bring frame, door and external mastic across several units into one programme.

What sealant work can’t fix
Being straight saves everyone time. New sealant won’t cure:
- Leaks through the frame itself rather than the perimeter
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Masonry that has broken away beside the joint
If you’re not sure, just ring 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

Site staff or a sealant specialist?
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Our process
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Ayot Green can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.
- First we look at the mastic on each building and note what needs replacing.
- 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.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Before we start on site
- Explain the parking and delivery arrangements
- Make sure the joints can be reached
- Send any specification or drawings in advance
