About our facade sealing in North Mundham
Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters, using sealants classified for facade or glazing use. Site teams most often ask us about gaps between rainscreen or cladding panels and new sealant peeling off old mastic, on perimeter joints where frames meet the structure, shopfront frames and stone and brick facade joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in North Mundham it comes down to the same thing: the right product in a properly prepared joint.
Conversions of older rural buildings near smaller places such as North Mundham bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Why it’s worth doing now in North Mundham
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts, often turning up far from the joint. Around North Mundham, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
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.

When it isn’t the sealant
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Damaged frames that need replacing
- Replacing glass or failed glazing units
- Leaks from roofs, gutters or failed flashings rather than sealant joints
If in doubt, ring 01277 525 020 or email the details over and we’ll say what we think.

New build and refits around North Mundham
With the shore within about 3 miles, North Mundham counts as a coastal location. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so joint design, primers and product choice deserve extra care. A number of hotels sit less than 2 miles from North Mundham. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.
Hospital estates such as St Richard's Hospital, 2.2 miles to the north of North Mundham, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Projects at schools like North Mundham Primary School work to term dates, so mastic is programmed tightly. When units on a site such as Quarry Lane Industrial Estate, 1.2 miles to the north of North Mundham, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

FAQs: North Mundham
Is North Mundham too far out for you?
No. Places such as North Mundham are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Can work at a site such as University of Chichester fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Are you CHAS accredited?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can staff carry on working while you are here?
Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.
Is old mastic on our building likely to contain asbestos?
In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed. Removal of asbestos isn’t something we do.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.

After the work
Keep the joints in good shape with a few simple steps:
- Inspect facade joints on a regular cycle
- Note when each elevation was last resealed
- Plan facade sealing alongside redecoration
- Avoid patch repairs on failed facade joints
Keep a note of which product went in and when. It helps when matching repairs or planning the next reseal.
Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in instead of after the damage.
Owners, agents and contractors
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
What the job involves on each surface
Perimeter joints at frames and structure
Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. Our work is that perimeter joint rather than the system it surrounds.
Brick and stone facades
Stone can absorb plasticisers from the wrong sealant. The specified stone-compatible sealant is what we use, with masked edges for a clean line.
Diagnose, treat, sign off
