Common problems we fix in Addlestone
Most facade joints fail through age and weathering. UV and weather harden the sealant until it can’t stretch with the building.
Clients typically get in touch after noticing something like this:
- Draughts around frames and panels
- Damp patches beside frames after rain
- Discoloured or dirty facade joints
- Old perimeter mastic that has dried out
For a contractor working at a hospital such as St Peter's Hospital A&E, 1.6 miles to the west of Addlestone, perimeter and facade sealing is planned around patients and deliveries.

About our facade sealing in Addlestone
Access is part of every facade job, and we plan it with you before quoting. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site, and we’ll fit the work around it. We work on coping and flashing joints, cladding panel joints and shopfront frames, and what we are called in for most is water coming in around window frames and failed seals around shopfront and entrance frames. Most enquiries from Addlestone 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.
In a smaller place such as Addlestone, construction tends to mean small housing schemes, conversions and extensions to community buildings. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.
Our workmanship is guaranteed for 12 months, in Addlestone as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Different surfaces, different methods
Brick and stone facades
On masonry, the sealant has to suit a porous, textured surface. We avoid acetoxy silicone, which can stain some natural stone, and primers go on where specified.
Cladding panel joints
On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end with backing and a facade-grade sealant.

New build and refits around Addlestone
Addlestone 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, which is why external dates are agreed with the site manager. The area within 2 miles of Addlestone holds a good number of hotels. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.
For contractors at a college like Brooklands Technical College - Weybridge Campus, which lies south-east of Addlestone, perimeters and internal sealant are timed for the holidays. For contractors on a campus like Royal Holloway University, 4.9 miles to the north-west of Addlestone, facade and perimeter sealing has to fit around students and term dates.

When to bring in a specialist
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Questions we’re asked in Addlestone
Is a smaller place like Addlestone outside your area?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Can you work at a site such as Bourne Business Park, by Addlestone?
Yes. We cover Addlestone and the area around it, including industrial estates, business parks and retail parks such as Bourne Business Park. Photos and a short description are enough for a first look.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
Can you fit around our working hours?
Mention the site’s hours and access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
How long does a job like this take?
That varies with the scale of the job, but the work normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. For bigger or phased jobs, we’ll set out a timescale with the quote.
Can the building stay open while you work?
Usually, yes. Phased work can be planned so areas stay in use.
On site: what to expect
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. What matters most for a job in Addlestone is a clear list of what needs doing. A fixed quote follows.
- First we review photographs, 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.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- 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
- Warn occupants and staff about the work

Maintenance after handover
Once the work is signed off, a little attention goes a long way:
- Plan facade sealing alongside redecoration
- Ask about asbestos in pre-2000 mastic
- Check that rainwater leaves the facade the way it was designed to
- Inspect facade joints on a regular cycle
Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead and tell your cleaning contractor.
Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail instead of after the damage.
