About our facade sealing in Lumley
We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip. We will tell you if we think the leak is coming from somewhere sealant won’t fix. The enquiries we see most involve failed sealant on precast panel joints and new sealant peeling off old mastic, across coping and flashing joints, shopfront frames and cladding panel joints. A single leaking joint is often how a building in Lumley first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places like Lumley, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

New build and refits around Lumley
The sea is no more than about 1 mile from Lumley. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so joint design, primers and product choice deserve extra care. Central London is about 58 miles from Lumley. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand.
When units on a site such as Central Retail Park, 2.4 miles to the west of Lumley, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. When a school such as St James Church of England Controlled Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. New wings at hospitals like Spire Hospital Portsmouth, 1.5 miles to the north-west of Lumley, bring long runs of window and panel joints to seal.
Lumley is about 1 mile east of Emsworth, in West Sussex. Our applicators travel to Lumley for work on facade joints. Across West Sussex, 373 places are covered, Lumley among them. Sites around Portsmouth have their own page, roughly 7 miles from Lumley.
Work on facade joints is covered throughout PO10, whatever the building. For a building on Lumley Road and Northlands Park or nearby, send details and we’ll quote for facade joints. If your building is just outside Lumley, we cover Emsworth (1 mile west), Westbourne (1 mile north), Southbourne (1 mile east), Woodmancote (1 mile north-east) and Denvilles (1 mile west). Further afield, our area takes in Bognor Regis (12 miles east), Chichester (7 miles east), Selsey (10 miles south-east), Portfield (7 miles east), Yapton (14 miles east) and East Wittering (7 miles south-east).

Common questions from Lumley clients
Would you work within a site like Spire Hospital Portsmouth?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Our building in Lumley is near the coast: does that change the sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.
Do you run new sealant over the existing bead?
No. A bead run over old sealant soon lifts. We remove the failed sealant, clean the faces, set the depth and reseal.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Are your applicators CSCS-carded?
Yes. If you need card details for site access, tell us and we will confirm them with the quote.
Will rain stop the work?
We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Cold, damp mornings can delay a start, and we build that into the programme.
Are you CHAS accredited?
Yes. We’re CHAS accredited and a Constructionline member.
Diagnose, treat, sign off
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Rural sites near Lumley may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- We start with photographs, drawings or a visit to see the joints and agree access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full and the joint faces cleaned.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- We go over the completed work with you before leaving.
Preparing the site
- Point out parking and an unloading spot
- Move anything stored against the joints
- Point out any areas we must not close

Different surfaces, different methods
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building, so preparation and product choice matter.
Cladding panel joints
Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface, often a low-modulus silicone or hybrid.
Why it’s worth doing now in Lumley
Topping up a failed joint normally buys very little time. A full cut-out and reseal costs more on the day but lasts much longer. For buildings around smaller places like Lumley, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Looking after the joints
Keep the joints in good shape with a few simple steps:
- Clear debris that holds water against joints
- Plan facade sealing alongside redecoration
- Investigate damp beside windows promptly
- Confirm the survey covers external sealants in older buildings
Following storms, look inside for damp or staining near frames. An early report typically means a small reseal rather than a bigger repair.
Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.
What affects the price in Lumley
Quotes vary with the job. Expect it to depend on:
- Travel to remote or island sites
- How accessible the joints are
- How much existing material needs removing
- Phasing around occupants
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Details that help us quote
For an accurate fixed quote, we need to understand the site. Useful things to include:
- How the joints are reached, and at what height
- The asbestos register, for older buildings
- Approximate linear metres or a joint schedule
- Specification clauses that apply
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.
What sealant work can’t fix
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Damp caused by condensation inside the building
- Installing or repairing glazing systems
- Cracked or spalling substrates that need repair before sealing
If in doubt, give us a call on 01277 525 020 or send photos by email and we’ll say what we think before you book.
