Aftercare for building managers
A few simple habits keep the new joints working:
- Start inspections with the most exposed faces
- Share the asbestos register when you send details
- Plan resealing building by building rather than complaint by complaint
- Mention RAMS, insurance or CSCS requirements up front
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order and work down the list.
Mastic sealing for commercial buildings in Widley
Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. The enquiries we see most involve open joints in brickwork or panels and no planned programme for sealant, across balcony and threshold joints, window and door perimeters on blocks and shopfronts below residential blocks. Searching for sealant specialists in Widley? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Around smaller places like Widley, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Leave it or put it right?
Failed perimeter mastic lets cold air in around frames and the windows typically get the blame. In many cases, new perimeter sealant deals with it when the frames themselves are sound. Around Widley, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we’ll quote for the lot.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Why choose Mastic Doctor in Widley
- Coloured sealants to suit the setting, where available

Common questions from Widley clients
Is Widley too small for you to travel to?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work at a site such as Railway Triangle Industrial Estate, by Widley?
Yes. Our area takes in Widley and its surroundings, with estates and business parks such as Railway Triangle Industrial Estate included. A few photographs and the unit address let us price the work.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can people stay in the building while you reseal?
Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.
What do you charge?
We don’t publish prices, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area.

What sets the cost
These are the things that shape the price:
- How much existing material needs removing
- Working within restricted access windows
- Specialist products, such as fire-rated or hygienic sealants
- Distance, for remote addresses
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.
Sending details for a quote
We can often quote from photos and a few details. It helps to include:
- Photos of the joints, close up and from further back
- Rough lengths or quantities, or drawings if you have them
- Any dates the work must fit around
- Anything awkward about access or site hours
Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Honest limits
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Frames that are rotten, warped or broken
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Roof leaks, gutters or failed flashings that aren’t sealant joints
If in doubt, call 01277 525 020 or email drawings and photos and we’ll say what we think.
Surfaces we seal
- Window and door perimeters on blocks
- Shopfronts below residential blocks
- Balcony and threshold joints
- Communal entrances and stairwells
- External wall and movement joints
- Communal kitchens and washrooms
Common problems we fix in Widley
Occasionally the substrate fails, not the sealant for example where render or brick edges crumble. We will tell you if the joint edges need repairing before resealing.
Any of the following is a good reason to get the joints checked over:
- Damaged joints in communal entrances and corridors
- Failed external movement joints
- Leaks at window and door perimeters
- A mix of products and colours from past repairs
Blocks of flats and mixed-use buildings often cluster around stations such as Cosham station (1.3 miles south-west of Widley) and their window and balcony mastic tends to age at the same rate across a building.
