Southfields: questions and answers
Will you take on work at estates like Rufus Business Centre, close to Southfields?
Yes. Estates, retail parks and business parks around Southfields, Rufus Business Centre among them, are all within reach. To start, just give us a call on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Is a hospital such as Royal Hospital for Neuro-Disability somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Is your workmanship covered by a guarantee?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it.
Do you seal facades in winter?
Wet joints or temperatures outside the product’s range mean waiting. We plan for weather and keep you updated.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Can you just add new sealant on top?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. Nothing else gives a bond that lasts.
About our facade sealing in Southfields
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure on commercial buildings in Southfields. Where sealant is the specified fix, we also take on coping and flashing joints. If you have facade joints cracked through the middle and cold air coming in at window perimeters, we can help, on shopfront frames, window and door perimeters and coping and flashing joints alike. Looking for mastic applicators who cover Southfields? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

When it isn’t the sealant
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Joints whose design needs changing by the specifier
- Damp caused by condensation inside the building
- Providing access systems for the work
If in doubt, call the office on 01277 525 020 or send photos by email and we will say what we think.
Where we work in Southfields
- Perimeter joints where frames meet the structure
- Window and door perimeters
- Stone and brick facade joints
- Coping and flashing joints
- Cladding panel joints
- Shopfront frames
What happens if it’s left?
The longer a failed joint is left, the more the substrate suffers: edges get wet, render and timber deteriorate and frames can move. Early action keeps it simple. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
A quote for facade joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

Sites and facades in and around Southfields
Plenty of hotels sit less than 2 miles from Southfields. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. As part of Greater London, Southfields is inside the ULEZ, which applies to every van on site. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.
For contractors at a college like South Thames College Wandsworth Campus, 0.7 miles north of Southfields, perimeters and internal sealant are timed for the holidays. Building work at universities like University of Roehampton (to the west of Southfields) is often timed for the summer, mastic included.
Southfields is about 2 miles north-east of Wimbledon, in Greater London. If you’re looking for facade sealing in Southfields, we can help. We work across 764 places in Greater London, from busy centres to rural villages. Our London page has more on work in that area.
We take on facade joints across the SW18, SW19 and SW17 postcode area. Buildings on Burr Road, Acuba Road and Mount Road are within our area. Just outside Southfields, we also work in Earlsfield (1 mile south-east), Wandsworth (1 mile north), Summerstown (1 mile south), Battersea (2 miles north-east) and Clapham Junction (2 miles north-east). Nearby towns on our patch include London (6 miles north-east), City of Westminster (5 miles north), Marylebone (5 miles north), Kensington (4 miles north), St Pancras (6 miles north-east) and Shoreditch (7 miles north-east).
What’s near Southfields
We work on buildings around Old Sergeant pub, Southfields Academy and Wandsworth School and the streets around them. Southfields has its own railway station: Earlsfield station. Nearby you’ll also find Royal Hospital for Neuro-disability (1 mile west) and Wimbledon Lawn Tennis Museum (1.2 miles south-west). For a walk, there’s Henman Hill and Wandle Meadow Nature Park.
What we are called out for in Southfields
The wrong product causes its share of trouble: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Most external joints call for a neutral-cure, facade-grade sealant.
It’s worth sending us details if you spot any of the following:
- Air leaks through failed facade joints
- Previous reseals run over old sealant
- Facade joints cracked through the middle
- Unsightly perimeter sealant on a visible elevation
Hotels like The Lodge Hotel, 0.9 miles to the north-west of Southfields, rarely close for long, so refurbishment mastic is phased floor by floor.
What your quote should include
- The terms of the workmanship guarantee
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- The named product and why it was chosen
- How the joint faces will be prepared and primed
What the job involves on each surface
Cladding panel joints
On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end.
Render and coated surfaces
Paintable sealants exist for joints that will be coated. The choice depends on the specification and finish.
Doing it in-house
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
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 easy to get wrong without experience.

Our process
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather. In Southfields, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- Photos, drawings or a visit tell us about the joints and the 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.
Getting the site ready
- Tell us what induction or permit system the site runs
- Tell staff and tenants when we will be in
- Make sure the joints can be reached
