What we can’t put right
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Joints too narrow for the movement they take, which need redesign
- Cracked or spalling substrates that need repair before sealing
- Providing access systems for the work
Not sure which it is? You can call the office on 01277 525 020 or email us and we will tell you honestly.

Facade sealing for commercial buildings in Whitchurch
Some clients need every window on a block resealed; others need a few leaking frames sorted. The approach doesn’t change with the size: old sealant out, faces cleaned, depth set and a new bead tooled in. Each job carries our 12-month guarantee. We work on shopfront frames, window and door perimeters and coping and flashing joints, and the failures we are asked to look at most are staining on stone next to old sealant and old perimeter mastic that has dried out. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Whitchurch is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around places like Whitchurch, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Why act early in Whitchurch
Scaffold or access already on site makes resealing much simpler. Coordinating facade sealing with other external works avoids paying for access twice. Small buildings around Whitchurch suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Your questions answered
Does your area include sites such as Ardglen Industrial Estate, near Whitchurch?
Yes. We cover Whitchurch and the area around it, including industrial estates, business parks and retail parks such as Ardglen Industrial Estate. Photos and a short description are enough for a first look.
Can the mastic package for our job in Whitchurch follow the site programme?
Yes, we work to the programme and the sequence the site sets. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you provide access for facade work?
That comes down to the access arranged for the job. When you give us a call on 01277 525 020 or use the quote form, describe the access, and we will plan the work with you.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
When to call us in Whitchurch
When the sealant tears down its centre, it has typically been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.
Typical triggers for a call:
- Leaks at window and door perimeters
- Previous reseals run over old sealant
- Staining on stone next to old sealant
- Perimeter joints where frames meet the structure
When a school such as Whitchurch Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.
Questions to ask before you book
- Are they CHAS accredited or on Constructionline?

Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
