FAQs: Woodside
Will you fit the mastic around our build programme in Woodside?
Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is Woodside too small for you to travel to?
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.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Do you take on mastic snagging only?
Yes, we can. Share the list and photos, and a fixed quote follows.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Do you guarantee new-build sealant work?
The work is guaranteed for 12 months on the workmanship. Keeping other trades off finished joints prevents most problems.
Construction mastic in Woodside
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old, and on older buildings we ask for the asbestos survey before disturbing anything. After that, the joints are prepared and sealed to the specification. If you have mastic snags holding up handover and perimeter gaps outside the sealant’s range, we can put it right, whatever the surface. Searching for sealant specialists in Woodside? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Conversions of older rural buildings near smaller places such as Woodside bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

What we can’t put right
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Damage to finishes by other trades after we’ve sealed
- Deciding which fire-stopping product a penetration needs
Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.

Sites and facades in and around Woodside
Woodside is about 63 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. Woodside sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager.

Cost factors for mastic packages
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Whether old sealant has to be cut out first
- Joint width, depth and condition
- The product specified
- Whether the work must be split into stages
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
What to include in your enquiry
For an accurate fixed quote, we need to understand the site. Useful things to include:
- Any dates the work must fit around
- Whether an asbestos survey exists
- Drawings or a marked-up plan, if available
- The product your specification calls for
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
Signs you need construction mastic in Woodside
Wide, tapered or inconsistent gaps around frames are a common problem. Every product has limits on how wide a joint it can bridge and gaps beyond it need packing or adjusting by the frame installer. Better to raise it at the start than seal a joint that’s bound to fail.
Typical triggers for a call:
- Frame gaps too wide for sealant alone
- Window and door perimeters that won’t pass inspection
- A mastic package split between trades with no clear owner
- Sealant knocked or painted over by other trades
For contractors at a school such as Vernham Dean Gillum's Church of England Primary School, sealing has to be finished before term starts.
Before you book anyone
- How the existing material will be dealt with
- Their pre-qualification and accreditations
- Do they follow the manufacturer’s priming guidance?
- Proof of insurance
After the work
For the best life from the joints:
- Allow flexibility for external sealing in damp or cold weather
- Ask installers to correct oversized gaps first
- Don’t schedule sealing before decorators and flooring are done
- Ask for joint and product checks before the package is urgent
After we’ve sealed an area, it helps to keep other trades from damaging the joints. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked.
Snag items left to the last week put handover at risk. Clearing snags area by area spreads the work out, and avoids a rush.
Different surfaces, different methods
Kitchens and utility areas
Commercial kitchens often need hygienic or food-safe sealants. We follow the specification and seal to a smooth, cleanable finish.
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. Fire stopping design belongs to the designer and building control and we install what’s specified.
