Facade sealing in Laleham, done properly
We don’t install glazing systems or replace glass. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds. Most enquiries involve air leaks through failed facade joints and staining on stone next to old sealant, on cladding panel joints, window and door perimeters and stone and brick facade joints. Most enquiries from Laleham start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
For a contractor on a smaller site near Laleham, one mastic visit at the right stage saves return trips. Tell us when scaffold comes down and when decoration finishes, and we’ll plan around those stages.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Diagnose, treat, sign off
We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Work in places the size of Laleham is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
Getting the site ready
- Agree which areas must stay open
- Explain the parking and delivery arrangements
- Make sure the joints can be reached

General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Commercial clients in Laleham
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Laleham can sit alongside others in a wider programme.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Building and refurbishing in Laleham
A 2-mile radius around Laleham takes in a good number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Laleham is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.
On a campus such as Royal Holloway University, which lies west of Laleham, new teaching buildings and residences are usually built and refurbished around the academic year. For a contractor at a hotel such as The Sunday Hotel Staines, which lies north-west of Laleham, the mastic often has to be finished before a reopening date.

When to call us in Laleham
Adhesive failure, where the sealant peels away from one face, usually comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.
Typical triggers for a call:
- Air leaks through failed facade joints
- Weathered joints at frame-to-structure perimeters
- Weathered facade joints that have lost their grip
- Discoloured or dirty facade joints
When units on a site such as Pine Trees Business Park, 1.6 miles to the north-west of Laleham, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

How the job changes by surface
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather, so preparation and product choice matter.
Window and door perimeters
Window and door perimeters make up most facade sealing work. A low-modulus neutral-cure product, chosen for the frame and wall, goes in finished to throw water off the joint.

FAQs: Laleham
Will you take on work at estates like Pine Trees Business Park, close to Laleham?
Yes. Estates, retail parks and business parks around Laleham, Pine Trees Business Park among them, are all within reach. A few photographs and the unit address let us price the work.
Is Laleham too far out for you?
No. Places such as Laleham are covered as much as the big towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you offer coloured sealant?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
What type of sealant goes on window perimeters?
It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing.
Is old mastic on our building likely to contain asbestos?
In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first. We don’t remove asbestos-containing materials.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Looking after the joints
After handover, these steps help:
- Keep the sealant details on the building file
- Clear debris that holds water against joints
- Never let anyone seal over old sealant
- Share access with other external trades
Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead, so brief your window cleaners.
Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money.
