About our mastic sealing in Mislingford
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. If you’re dealing with complaints coming in block by block and leaks at window and door perimeters, we can put it right, whatever the surface. A single leaking joint is often how a building in Mislingford first comes to us: we look at the rest while we are there and tell you what we find.
For owners with a single building near Mislingford, we plan to finish in one visit where possible. Send photos of the frames and joints and we will give a fixed quote.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:
- Leaks through the frame itself rather than the perimeter
- Water coming in from the roof or rainwater goods
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If in doubt, ring 01277 525 020 or email the details over and we will say what we think before you book.

Keeping the joints sound
A few simple habits keep the new joints working:
- Make mastic part of routine maintenance checks
- Log resealing dates block by block
- Prioritise elevations facing the weather
- Protect low-level joints in entrances
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
Joints on a building age together so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
What happens if it’s left?
Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish. Converted and older buildings near places like Mislingford tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

- A mix of products and colours from past repairs

Mastic sealing in Mislingford: the local picture
The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first. Mislingford is about 61 miles from central London. Within reach of London, blocks run by agents and associations are common around stations.
If you own or manage units on a site such as Waltham Business Park, 1 mile north-west of Mislingford, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. If your remit includes a building such as Swanmore College of Technology, frame and door mastic can be programmed for the holidays.

Questions we’re asked in Mislingford
Is Waltham Business Park, near Mislingford, within your area?
Yes. Estates, retail parks and business parks around Mislingford, Waltham Business Park among them, are all within reach. Photos and a short description are enough for a first look.
Is Mislingford too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
How do we ask for a quote?
The quote form is the simplest route, though you can also speak to us on 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
