About our mastic sealing in Waterford
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. Site teams most often ask us about leaks at window and door perimeters and cracked, hardened mastic round windows on a block, on communal kitchens and washrooms, balcony and threshold joints and shopfronts below residential blocks. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Waterford it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places like Waterford, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Looking after buildings in and around Waterford
Waterford is about 22 miles from central London. Managed blocks of flats are a big part of commuter-belt property. Rainfall across the South East, Waterford 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 typically need attention first.
Older buildings near Waterford, from historic houses such as Digswell House, 4.7 miles west of Waterford, to more modest stock, need compatible products when frames are resealed. Older community buildings, Church of St Michael and All Angels among them, often have frames of mixed ages whose mastic varies.

What we can’t put right
Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:
- Substrate edges that need repairing first
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Failed window or door frames, which need a window contractor
If you’re not sure, just call 01277 525 020 or use the quote form and we will give you a straight answer before you book.
What we seal
- Shopfronts below residential blocks
- External wall and movement joints
- Communal kitchens and washrooms
- Balcony and threshold joints
- Window and door perimeters on blocks
- Communal entrances and stairwells
Site staff or a sealant specialist?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Common problems we fix in Waterford
Sunlight and weather break mastic down over time. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.
What tends to prompt an enquiry:
- Repeated reactive repairs to the same buildings
- Occupiers reporting cold air round windows
- A mix of products and colours from past repairs
- Failed external movement joints
Schools and community buildings such as Bengeo Primary School need frame and external mastic kept sound like any building.

Why it’s worth doing now in Waterford
Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish and one 12-month guarantee. For buildings around smaller places like Waterford, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

Waterford: questions and answers
Do you cover business parks and estates near Waterford, such as Warrenwood Industrial Estate?
Yes. Our area takes in Waterford and its surroundings, with estates and business parks such as Warrenwood Industrial Estate included. To start, just call 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Is Waterford too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
What paperwork can you provide?
We’re CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn with dates agreed in advance.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Surface by surface
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
Window and door perimeters on blocks
On most blocks, the frame-to-wall joint is where failure shows first. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.
