When to call us in North Waltham
Much failed sealant was laid on dirty, dusty or damp surfaces. Without clean, sound faces and a primer where the product needs one it comes away from one face.
Look out for the following:
- The same joint failures repeated across a portfolio
- Cracked, hardened mastic round windows on a block
- Draughts at frames across a block
- Complaints coming in block by block
If your remit includes a building such as North Waltham Primary School, frame and door mastic can be programmed for the holidays.

Mastic sealing in North Waltham
For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card and we hold public liability insurance. Resealed mastic joints in North Waltham carry our 12-month guarantee. If you’re dealing with movement joints with sealant missing and mastic failing across several blocks on an estate, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in North Waltham, that means joint design, primers and backing rod as standard.
Owners and agents with buildings around smaller places such as North Waltham 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.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

More services for North Waltham
For owners and agents in North Waltham
At about 51 miles from central London, North Waltham is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide. Rainfall across the South East, North Waltham included, is lower than in many parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.
If you look after a block within reach of Micheldever station, 3.6 miles south-west of North Waltham, frame and balcony mastic can be renewed on one programme. Churches, halls and community buildings such as Church of St. Michael's are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Aftercare for building managers
A few simple habits keep the new joints working:
- Make it easy for occupiers to report draughts
- Keep a record of when each building was resealed
- Reduce knocks to communal area joints
- Avoid piecemeal callouts where you can
Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.
Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings and work down the list.
Questions we’re asked in North Waltham
Will you price a mastic programme across our North Waltham portfolio?
Yes, we quote for single buildings and for programmes across several blocks. Send the addresses and photographs and we will give a fixed quote.
Can you quote for a block close to Micheldever station?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
Can you take on resealing for a block portfolio?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.
How long do sealant joints last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Can you seal joints high up on a block?
Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place and we will confirm the approach in the quote.
How many days will you need on site?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Leave it or put it right?
Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows and occupiers notice. Converted and older buildings near places like North Waltham tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
A quote for mastic joints depends on quantities, condition and access, plus any specification you are working to. Ask us for a fixed quote.

For managing agents and facilities managers
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
How the job changes by surface
Window and door perimeters on blocks
Perimeter joints on blocks are best done elevation by elevation or block by block. Access is agreed with you before the quote is fixed.
Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos and the register is checked before anything is disturbed. Suspect material is tested before work continues.
Our process
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us.
