Mastic sealing in Higham Hill, done properly
Before work starts, most agents and landlords want the documents in order. 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, with public liability insurance. The enquiries we see most involve communal area joints that look neglected and the same joint failures repeated across a portfolio, across balcony and threshold joints, shopfronts below residential blocks and window and door perimeters on blocks. For commercial sealant work in Higham Hill, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
For managing agents in Higham Hill, resident access, notice periods and the building’s rules shape the job. We work to the agent’s notice and access plan, so residents know what’s happening.
Work we carry out in Greater London comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or email the details over and we will come back to it.

When to call us in Higham Hill
Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. We will tell you if the joint edges need repairing before resealing.
Things that normally lead to an enquiry:
- Movement joints with sealant missing
- Draught complaints from residents or tenants
- Patchy repairs in mismatched sealant
- No planned programme for sealant
If you’re responsible for a building such as St Andrew's Christian Centre, frame and door mastic needs the same attention as any other property.
What your quote should include
- Which product they’ll use, and why it suits the joint
- Who will actually carry out the work
- Health and safety accreditation such as CHAS
- How the joint faces will be prepared and primed
From enquiry to sign-off
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Old sealant is stripped and each face prepared back to firm material.
- 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
- Send asbestos survey details if the building is pre-2000
- Let us know about inductions and permits
- Tell staff and tenants when we will be in

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Why it’s worth doing now in Higham Hill

Getting scaffold, permits or access booked in Higham Hill takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
A quote for mastic joints depends on quantities, condition and access. Ask us for a fixed quote.

Your questions answered
Do you take on jobs in Higham Hill where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we’ll work to them.
Do you work in occupied care homes around Higham Hill?
Yes. Care settings are planned area by area, at times agreed with the home. We follow the home’s own procedures throughout.
What guarantee do you give on resealing?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
How do you reach windows on upper floors?
Every block is different. We agree access with you at quote stage so the fixed quote reflects it.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.
What do you charge?
Every job gets its own fixed quote. To get one, call 01277 525 020 or send photos by email with a description of the work.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
What we can’t put right
Some faults sit outside our scope, and we say so rather than covering them up:
- Masonry that has broken away beside the joint
- Leaks from above rather than through a joint
- Leaks through the frame itself rather than the perimeter
Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we’ll tell you honestly before you book.
Where we work in Higham Hill
- External wall and movement joints
- Window and door perimeters on blocks
- Shopfronts below residential blocks
- Communal entrances and stairwells
- Communal kitchens and washrooms
- Balcony and threshold joints
Maintenance after handover
To get the most from the new sealant:
- Reduce knocks to communal area joints
- Have the asbestos survey to hand for older buildings
- Ask residents or tenants to report leaks and draughts early
- Include mastic in your cyclical inspections
Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
Joints on a building age together, so it pays to look at the whole elevation. Doing them together saves going back again and again.
