Mastic sealing in Wendover
Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Communal entrances and stairs stay usable throughout. If you’re dealing with no planned programme for sealant and cracked, hardened mastic round windows on a block, we can help. Searching for sealant specialists in Wendover? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Converted and older buildings in and around Wendover often put modern windows into old walls. The mastic there needs to suit both surfaces.

Maintenance after handover
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Avoid piecemeal callouts where you can
- Mention RAMS, insurance or CSCS requirements up front
- Log resealing dates block by block
- Reduce knocks to communal area joints
Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.
Joints on a building age together, so it pays to look at the whole elevation. Doing them together saves going back again and again.
What we’re called out for in Wendover
The edges of the material itself sometimes break away for example where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.
Look out for the following:
- Complaints coming in block by block
- A mix of products and colours from past repairs
- Open joints in brickwork or panels
- Brittle perimeter mastic across a building
Churches, halls and community buildings such as 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.
Before you book anyone
- How they handle RAMS and site documents
- Health and safety accreditation such as CHAS
- What the guarantee covers, and for how long
- The named product and why it was chosen
How a job runs
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. What matters most for a job in Wendover is a clear list of what needs doing. A fixed quote follows.
- Each block or building is walked and the failed joints recorded with the likely cause.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Old sealant is stripped and each face prepared back to firm material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Before we start on site
- Agree which areas must stay open
- Let building users know which areas are affected

Advice
Wendover: questions and answers
Is Wendover off your patch?
Not at all: smaller places are covered as well as towns. 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.
Does your area include sites such as Station Approach Business Park, near Wendover?
Yes. We cover Wendover and the area around it, including industrial estates, business parks and retail parks such as Station Approach Business Park. To start, just call 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
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’ll tell you how we’d approach it.
Can you quote from photos?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Looking after buildings in and around Wendover
Wendover sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Central London is about 33 miles from Wendover. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate.
If you look after a block within reach of Wendover station, under half a mile south-west of Wendover, frame and balcony mastic can be renewed on one programme. Owners of student blocks near University Campus Aylesbury Vale (to the north-west of Wendover) can schedule frame and external mastic for the summer vacation.

What affects the price in Wendover
There’s no standard rate for sealant work, because every site is different. What we look at:
- Quantities, in metres or numbers
- Distance, for remote addresses
- The size and state of each joint
- Access and working height
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Sending details for a quote
However big the job, these details speed things up:
- Any dates the work must fit around
- Whether the building will be occupied during the work
- Photos of the joints, close up and from further back
- Access details, including height
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Leaks from above rather than through a joint
- Materials that need asbestos testing before work
- Failed window or door frames, which need a window contractor
If in doubt, speak to us on 01277 525 020 or email us and we’ll say what we think before you book.
What we seal
- External wall and movement joints
- Balcony and threshold joints
- Window and door perimeters on blocks
- Communal entrances and stairwells
- Communal kitchens and washrooms
- Shopfronts below residential blocks
Why deal with it now?
Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. Small buildings around Wendover suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you are ready.
