Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a job in Bushey Heath, the main thing is a clear picture of the work, so send photos of each area. A fixed quote follows.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- 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.

Mastic sealing for commercial buildings in Bushey Heath
Owners and agents typically 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. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. We work on window and door perimeters on blocks, communal entrances and stairwells and balcony and threshold joints, and the usual reasons a site gets in touch are failed external movement joints and patchy repairs in mismatched sealant. Whether you call it commercial sealant work, mastic application or joint sealing, in Bushey Heath it comes down to the same thing: the right product in a properly prepared joint.
Older buildings and conversions around places like Bushey Heath mix old masonry with newer frames. The mastic there needs to suit both surfaces.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or send details through our quote form and we’ll come back to it.

Why act early in Bushey Heath
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. For buildings in places like Bushey Heath, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.
Why us?
- Failed material removed, not covered up
- One phone line for London, the South East and Scotland

- Commercial sealant work since 2005

General trades versus a 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. A poor seal in places like these tends to cost more to put right later.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
What we can’t put right
Honesty saves time and money. Fresh joints won’t solve:
- Water coming in from the roof or rainwater goods
- Failed window or door frames, which need a window contractor
- Asbestos-containing sealant, which we don’t remove
If in doubt, ring 01277 525 020 or send details through our quote form and we’ll say what we think.
Joints and surfaces we work on
- Balcony and threshold joints
- External wall and movement joints
- Shopfronts below residential blocks

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
Mastic sealing in Bushey Heath: the local picture
Bushey Heath lies roughly 14 miles out from central London. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate. Rainfall across the South East, Bushey Heath included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building usually need attention first.
Older community buildings, Church of St Peter among them, often have frames of mixed ages whose mastic varies. If you manage student housing near a university such as Westminster University, 4.1 miles south of Bushey Heath, the summer turnaround is the time for mastic. For owners of several units at places like Lismirrane Industrial Park, 1.3 miles north-east of Bushey Heath, one programme can deal with frame and external mastic across the lot.
Bushey Heath is about 1 mile south-east of Bushey, in Hertfordshire. Anywhere in WD23, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. 371 places across Hertfordshire fall within our area, Bushey Heath among them. We also cover London, around 14 miles from Bushey Heath.

Quoting for work in Bushey Heath
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Joint width, depth and condition
- Any access equipment needed
- The total length or number of joints
- How much existing material needs removing
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
What to include in your enquiry
However big the job, the same details help:
- Specification clauses that apply
- When you need the work done
- Anything awkward about access or site hours
- Asbestos survey details if the building is older
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, ring 01277 525 020 or email a schedule or drawings.
Questions we’re asked in Bushey Heath
Can you quote for a block close to Carpenders Park station?
Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Is Bushey Heath off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
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 paperwork can you provide?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
How do you handle work on occupied blocks?
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.
Do you check for asbestos in old sealant?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
