How we handle facade sealing in Woodside
Facade sealants sit in the sun, rain and frost every day, so they don’t last indefinitely. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. We work on shopfront frames, perimeter joints where frames meet the structure and cladding panel joints, and the usual reasons a site gets in touch are draughts around frames and panels and weathered joints at frame-to-structure perimeters. Searching for sealant specialists in Woodside? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
In a smaller place such as Woodside, construction tends to mean small housing schemes, conversions and extensions to community buildings. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
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.

Keeping the joints sound
Cleaning and maintenance staff play a part too. Pass these on to them:
- Brief window cleaners about newly sealed joints
- Walk the elevations once or twice a year
- Plan facade sealing alongside redecoration
- Keep the sealant details on the building file
Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.
Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones.

Leave it or put it right?
Failed joints let in more than water: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. Small buildings around Woodside suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
A quote for facade joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Take a look at how commercial sealant jobs are priced and how we’re accredited.
Diagnose, treat, sign off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes a day or two for a few elevations, and longer where access has to be moved around the building, and we clear our waste as we work. For a site in Woodside, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
Preparing the site
- Arrange parking or a loading space
- Clear stock, furniture or equipment away from the joints
- Tell us what induction or permit system the site runs

Your questions answered
Can you work at a site such as Hill Farm Avenue Industrial Estate, by Woodside?
Yes. We cover Woodside and the area around it, including industrial estates, business parks and retail parks such as Hill Farm Avenue Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.
Can you work on a hospital site such as Leavesden Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Should we check old sealant for asbestos?
For older buildings, yes, check before work starts. The dutyholder holds the asbestos register, and we will ask to see it. If asbestos is suspected, work stops until it is tested.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.
Can you work on upper floors?
Access is planned with you before we quote. Let us know what access is in place or planned, and we’ll price the work around it.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
What sets the cost
What shapes the price:
- The size and state of each joint
- How much existing material needs removing
- Whether the work must be split into stages
- Location, for remote and island sites
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Details that help us quote
A few photographs plus some basic facts will normally do. It helps to include:
- Asbestos survey details if the building is older
- A wide shot and a close-up of the area
- When you need the work done
- Whether the building will be occupied during the work
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
Common problems we fix in Woodside
Three-sided adhesion is a classic installation fault. Without rod or bond-breaker tape, the bead is held back and tears as the joint moves.
Look out for the following:
- Facade joints cracked through the middle
- Old perimeter mastic that has dried out
- Cladding panel joints that have opened up
- Draughts around frames and panels
Hotels like Hunton Park Hotel (1 mile west of Woodside) rarely close for long, so refurbishment mastic is phased floor by floor.
Questions to ask before you book
- Is the sealant right for the movement and the substrate?
- Their plan for phasing and protecting the area
- Their pre-qualification and accreditations
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Building and refurbishing in Woodside
Woodside is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager. The area within 2 miles of Woodside holds several hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
Projects at schools like Alban Wood Primary School and Nursery work to term dates, so mastic is programmed tightly. When units on a site such as Hill Farm Avenue Industrial Estate, under half a mile to the west of Woodside, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
