Leave it or put it right?
If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice. In a smaller place such as North End, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Facade sealing in North End, done properly
Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. We work on stone and brick facade joints, shopfront frames and cladding panel joints, and what we’re called in for most is failed seals around shopfront and entrance frames and cladding panel joints that have opened up. For commercial sealant work in North End, you deal with one contact from quote to sign-off, whether it’s one building or several.
Conversions around smaller places like North End often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.
Our workmanship is guaranteed for 12 months, in North End as everywhere else we work. If our installation lets you down in that time, we return and fix it.

North End: questions and answers
Our building in North End is near the coast: does that change the sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Is a smaller place like North End outside your area?
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.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
How is access to upper-level joints handled?
That comes down to the access arranged for the job. Share what access exists or is planned when you send details.
Can you find out why a window is leaking?
Yes. Photos help, and you can phone 01277 525 020 or email the details over to arrange a visit. Failed perimeter sealant is a common cause, but not the only one, and we will be honest about which it is.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
From enquiry to sign-off
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. For a site in North End, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- We plan access and the order of elevations with the client.
- We only seal when joints are dry and within the product’s temperature range.
- Each joint is cut out and the edges inspected.
- Faces are cleaned, primed where needed and backed.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- We hand over with our 12-month workmanship guarantee.
Preparing the site
- Explain the parking and delivery arrangements
- Make sure the joints can be reached
- Tell us your opening times and when work is allowed

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

Sites and facades in and around North End
North End sits close to the coast, within about 1 mile. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Plenty of hotels sit less than 2 miles from North End. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
Hotel extensions and refits, at places such as The Avenue Hotel (less than half a mile north-west of North End), typically run between busy periods, so the sealing is squeezed into short windows. Units on estates such as Victory Retail Park, 0.7 miles south-west of North End, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Building work at universities like University of Portsmouth - North Zone, 1.5 miles to the south-west of North End, is often timed for the summer, mastic included.
North End is about 1 mile north of Portsmouth, in Portsmouth. Across the PO2 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. North End is one of 19 places in Portsmouth on our list for facade joints.

What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:
- Damp caused by condensation inside the building
- Work on the window or framing system itself
- Damaged frames that need replacing
If you’re not sure, just call 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Shopfront frames
- Stone and brick facade joints
- Perimeter joints where frames meet the structure
- Coping and flashing joints
- Window and door perimeters
- Cladding panel joints
Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Never let anyone seal over old sealant
- Confirm the survey covers external sealants in older buildings
- Plan facade sealing alongside redecoration
- Clear debris that holds water against joints
After heavy weather, check vulnerable elevations for signs of water inside. Catching a new leak early keeps the repair small.
Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.
