Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Diagnose, treat, sign off
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Several jobs near Ash can be grouped on one trip. Mention the building’s opening times and we will work within them.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
Getting the site ready
- Have the specification and drawings to hand
- Let us know about inductions and permits
- Move anything stored against the joints

About our facade sealing in Ash
We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause, though that isn’t the only cause. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. The enquiries we see most involve cold air coming in at window perimeters and weathered facade joints that have lost their grip, across shopfront frames, stone and brick facade joints and coping and flashing joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Ash it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In a smaller place such as Ash, construction tends to mean small housing schemes, conversions and extensions to community buildings. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

For managing agents and facilities managers
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Surface by surface
Render and coated surfaces
Rendered and painted facades need a sound edge for the sealant to bond to. We remove flaking material so the bead bonds to a firm surface.
Brick and stone facades
Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one.
What we can’t put right
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Damp caused by condensation inside the building
- Damaged frames that need replacing
- Arranging specialist high-level access, which is planned with the client
If in doubt, call 01277 525 020 or email us and we will say what we think before you book.

Questions about Ash
Can you work at a site such as Belle Vue Enterprise Centre, by Ash?
Yes. Estates, retail parks and business parks around Ash, Belle Vue Enterprise Centre among them, are all within reach. To start, just call the office on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Is a smaller place like Ash outside your area?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can staff carry on working while you are here?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, which many sites require.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Is old mastic on our building likely to contain asbestos?
For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder, so ask for it before we start. Suspect material is left alone until it has been tested.
When to call us in Ash
Sometimes the substrate is the problem: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.
These are often picked up first by site or facilities staff:
- Water coming in around window frames
- Gaps between rainscreen or cladding panels
- Perimeter sealant that has split or peeled away
- Failed seals around shopfront and entrance frames
New wings at hospitals like Guildford Hospital (to the east of Ash) bring long runs of window and panel joints to seal.
Questions to ask before you book
- What site paperwork they can supply
- Their pre-qualification and accreditations
- Whether old or failed sealant will be cut out, not overlaid
- Will CSCS-carded applicators be on site?
When to bring in a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces 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.
Facade sealing in Ash: the local picture
At about 32 miles from central London, Ash is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. Rainfall across the South East, Ash included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.
Hotels like Hog's Back Hotel (1.3 miles south of Ash) rarely close for long, so refurbishment mastic is phased floor by floor. Further education sites such as Aldershot College, 0.7 miles to the west of Ash, are extended and refurbished from time to time, with mastic often programmed into the summer break.
Ash is about 2 miles east of Aldershot, in Surrey. We cover Ash and the rest of Surrey, with the same fixed quotes and 12-month guarantee as everywhere else. 379 places across Surrey fall within our area, Ash among them. We also cover Reading, around 18 miles from Ash.
