Why act early in Boundstone
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once and is simpler to manage and budget. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Why appoint us
- One contact handling all your sites
- Fixed quotes based on photos, drawings or a visit
- Over 20 years of commercial sealing
- Fully insured

Common problems we fix in Boundstone
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Cleaning products add to the wear.
Common reasons buildings call us in:
- Leaks at window and door perimeters
- Patchy repairs in mismatched sealant
- Communal area joints that look neglected
- Draught complaints from residents or tenants
Student accommodation around universities such as University for the Creative Arts (1.8 miles north of Boundstone) is usually managed block by block, which suits a planned mastic programme.
What to look for in a quote
- Are they CHAS accredited or on Constructionline?

Blocks and managed buildings in Boundstone
Boundstone sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first. Boundstone is about 38 miles from central London. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate.
Blocks of flats and mixed-use buildings often cluster around stations such as Farnham station (1.7 miles north-east of Boundstone) and their window and balcony mastic tends to age at the same rate across a building. If you own or manage units on a site such as Grovebell Industrial Estate, 0.8 miles north of Boundstone, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.
Boundstone is about 2 miles south-west of Farnham, in Surrey. Our applicators travel to Boundstone for work on mastic joints. We work across 379 places in Surrey. For work in that direction, see our Reading page (19 miles or so).

Local landmarks in Boundstone
We work on buildings around Edgeborough School, Weydon School and Underdown nature reserve and the streets around them. Boundstone’s nearest station is Farnham station, about 1.7 miles north-east of the centre. Other landmarks nearby include Farnham Castle (2 miles north) and Museum of Farnham (1.6 miles north). Green spaces nearby include Culverswell Hill and Farnham Heath.
Looking after the joints
To get the most from the new sealant:
- Protect low-level joints in entrances
- Include mastic in your cyclical inspections
- Ask residents or tenants to report leaks and draughts early
- Look at the sunniest and most exposed elevations first
Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over unless told otherwise.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
On site: what to expect
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes anything from a day to a few weeks, depending on the number of buildings and joints. For a job in Boundstone, the main thing is a clear picture of the work, so send photographs of each area. You will then get a fixed price for the work.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
What we need from you
- Let building users know which areas are affected
- Move anything stored against the joints
- Send your site hours and access windows
