What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Water coming in from the roof or rainwater goods
- Materials that need asbestos testing before work
- Frames that are rotten, warped or broken
If in doubt, ring 01277 525 020 or send photos by email and we will say what we think.
Joints and surfaces we work on
- Communal kitchens and washrooms
- Balcony and threshold joints
- Shopfronts below residential blocks
- Communal entrances and stairwells
- Window and door perimeters on blocks
- External wall and movement joints
Mastic sealing in Lidsey
Owners and agents normally inherit a building’s mastic rather than choose it, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow along with complaints. We work on external wall and movement joints, communal entrances and stairwells and window and door perimeters on blocks, and the usual reasons a site gets in touch are the same joint failures repeated across a portfolio and window mastic that has split and shrunk. Searching for sealant specialists in Lidsey? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
For owners with a single building near Lidsey, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

After the work
Problems stay small when the joints are checked regularly. Specifically:
- Plan resealing building by building rather than complaint by complaint
- List the paperwork your organisation requires when you send details
- Reduce knocks to communal area joints
- Check the asbestos register before any old mastic is disturbed
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.

Lidsey: questions and answers
Our building in Lidsey is near the coast: does that change the sealant?
It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Will you take on a block within reach of Barnham station?
Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.
Do you work with property factors and landlords?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.
Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
Can you seal joints high up on a block?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Will residents or tenants be disturbed?
Residents and tenants carry on as normal. If any flats or units need access, we will tell you in advance so it can be arranged.
For managing agents and facilities managers
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Lidsey can sit alongside others in a wider programme.
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Why deal with it now?
Reacting to every complaint means sending someone out block by block. A planned programme treats each building once, under a single quote and a single programme. One visit to deal with every failing joint makes more sense than several trips to a place like Lidsey, rather than one at a time. Send photos of each area and we’ll quote for the lot.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Why us?
- Health and safety: CHAS accredited
- Work to your specification and the manufacturer’s guidance
- Colours confirmed for the specified product
- CSCS-carded applicators
Planned mastic for Lidsey portfolios
With the shore within about 3 miles, Lidsey counts as a coastal location. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints. Lidsey is about 53 miles from central London. Within reach of London, blocks run by agents and associations are common around stations.
Churches, halls and community buildings such as The Parish Church of St Mary are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Property owners at sites such as Saltbox Business Park. (0.9 miles south of Lidsey) can have mastic renewed between lettings.
