Facade sealing for commercial buildings in North Street
External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits. We plan for that and keep you updated. We work on perimeter joints where frames meet the structure, window and door perimeters and cladding panel joints, and what we are called in for most is hard, chalky sealant that no longer flexes and damp patches beside frames after rain. Most enquiries from North Street start with one failed joint and grow into a wider look at the building: 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 North Street, building work typically 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.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

From enquiry to sign-off
Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For a building around North Street, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- We start with photos, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full and the joint faces cleaned.
- Primer goes on where the product data asks for it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
Preparing the site
- Tell staff and tenants when we will be in
- Clear stock, furniture or equipment away from the joints
- Share the asbestos register for older buildings

Advice
Building owners, agents and FMs in North Street
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in North Street can sit alongside others in a wider programme.
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.
When to bring in a specialist
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- Confirm the survey covers external sealants in older buildings
- Avoid harsh cleaners on facade sealant
- Investigate damp beside windows promptly
- Avoid patch repairs on failed facade joints
Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness; record the locations.
Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in instead of after the damage.
What sets the cost
To price the job, we consider:
- The product specified
- Phasing around occupants
- Travel to remote or island sites
- How accessible the joints are
A quote for facade joints depends on quantities, condition and access. Ask us for a fixed quote.
What we need to price the job
For an accurate fixed quote, we need to understand the site. Useful things to include:
- Whether an asbestos survey exists
- Approximate linear metres or a joint schedule
- What the building is and how it’s used
- When you need the work done
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, call 01277 525 020 or email the details over.

When to call us in North Street
When the sealant tears down its centre, it has usually been asked to move more than it can. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.
Clients normally get in touch after noticing something like this:
- Patch repairs that keep failing
- Leaks at window and door perimeters
- Facade joints cracked through the middle
- Staining on stone next to old sealant
Extensions at sites like Alton Community Hospital (to the north-east of North Street) usually sit beside working departments, and the mastic follows strict access rules.

Questions we’re asked in North Street
Is Lower Soldridge Business Park, near North Street, within your area?
Yes. We cover North Street and the area around it, including industrial estates, business parks and retail parks such as Lower Soldridge Business Park. A few photos and the unit address let us price the work.
Is North Street off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Do you install glazing systems?
No. That work needs a glazing specialist. We reseal window perimeters, panel joints and frame-to-structure perimeters.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Which sealant will you use?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Are you insured?
Yes. We are fully insured, and the certificate can go with your quote.
Is your workmanship covered by a guarantee?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.
Building and refurbishing in North Street
North Street sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team. At about 51 miles from central London, North Street is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.
For contractors refurbishing units at places like Lower Soldridge Business Park, which lies north-east of North Street, the mastic covers cladding panels, roller-door and window perimeters. Historic houses such as Bentworth Hall (3.9 miles north of North Street) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
