Blocks and managed buildings in Bunkers Hill
Bunkers Hill lies roughly 58 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. The South East is one of the drier parts of the UK. 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.
Site managers at schools like Marlborough School can fit frame mastic into the summer works. Churches, halls and community buildings such as Church of Holy Cross are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. With historic buildings such as Blenheim Palace, 2.3 miles south-west of Bunkers Hill, in the wider area, owners of older properties around Bunkers Hill should expect mastic to need a product that suits old masonry.

Mastic sealing for commercial buildings in Bunkers Hill
For blocks and buildings in Bunkers Hill and across Oxfordshire, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote or we can visit. If you have complaints coming in block by block and movement joints with sealant missing, we can put it right, whatever the surface. Most enquiries from Bunkers Hill start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Owners and agents with buildings around smaller places such as Bunkers Hill 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.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

General trades versus a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Your questions answered
We manage a building near Tackley station. Can you help?
Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Is Bunkers Hill too far out for you?
Not at all. Bunkers Hill is within our area. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Will residents or tenants be disturbed?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
Can you seal joints high up on a block?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.
Can you reseal a whole block or estate?
We can. We survey and price each building, then work through them in order starting wherever is most urgent.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
What guarantee do you give on resealing?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- Quantities, in metres or numbers
- Any access equipment needed
- Joint width, depth and condition
- Whether old sealant has to be cut out first
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.
Before you send an enquiry
The more we know, the firmer the quote. Helpful details to send:
- How the joints are reached, and at what height
- The type of building and who uses it
- When you need the work done
- The postcode of the building
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.
Keeping the joints sound
After handover, a little attention goes a long way:
- Include mastic in your cyclical inspections
- Plan resealing building by building rather than complaint by complaint
- Reduce knocks to communal area joints
- Encourage occupiers to report problems at frames
Where a paintable product was specified, it can be painted after curing. Silicone typically can’t be painted, so keep decorators off it unless told otherwise.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and the complaints that come with it.
Why act early in Bunkers Hill
Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. One visit to deal with every failing joint makes more sense than several trips to a place like Bunkers Hill. Photos of every joint help us quote for the whole job.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Why appoint us
- A fixed quote before work starts

Our process
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Bunkers Hill are typically planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- We inspect each building and record the joints that have failed.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- 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.
Getting the site ready
- Move anything stored against the joints
- Point out any areas we must not close
- Explain the parking and delivery arrangements
