Facade sealing in Nether Wallop
We don’t install glazing systems or replace glass. We handle the sealant joints that surround those elements: perimeter joints where frames meet the structure, panel joints and window perimeters with products suited to facade or glazing perimeter joints. We work on window and door perimeters, perimeter joints where frames meet the structure and cladding panel joints, and what we’re called in for most is discoloured or dirty facade joints and new sealant peeling off old mastic. Looking for mastic applicators who cover Nether Wallop? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Construction in and around smaller places such as Nether Wallop is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Every job we finish is backed by a 12-month workmanship guarantee, in Nether Wallop as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Why deal with it now?
If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice, which is often the biggest saving. One visit to deal with every failing joint makes more sense than several trips to a place like Nether Wallop. Send photographs of each area and we will quote for the lot.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

FAQs: Nether Wallop
What site paperwork comes with a job in Nether Wallop?
We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.
Can you work to our programme on a site in or near Nether Wallop?
Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Do you run new sealant over the existing bead?
No. A bead run over old sealant soon lifts. We remove the failed sealant, clean the faces, set the depth and reseal.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
On site: what to expect
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and we clear our waste as we work. If others near Nether Wallop need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
- We start with photos, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full and both faces cleaned back.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
Before we start on site
- Share your working hours and any access restrictions
- Confirm the product named in the specification
- Point out parking and an unloading spot
Ask for a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.
Advice
How the job changes by surface
Window and door perimeters
Perimeter joints move as frames expand and contract in the sun. Rod placed at the right depth lets the bead stretch as the frame moves.
Render and coated surfaces
Sealant can only hold as well as the render or paint beneath it. We remove flaking material so the bead bonds to a firm surface, and areas needing repair are flagged.
Facades, frames and programmes in Nether Wallop
At about 69 miles from central London, Nether Wallop is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand. Nether Wallop sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.
For contractors at a school such as Wallop Primary School, sealing has to be finished before term starts.

Common problems we fix in Nether Wallop
Most facade joints fail through age and weathering. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, and cracks or adhesion loss follow.
Look out for the following:
- Perimeter joints where frames meet the structure
- Gaps between rainscreen or cladding panels
- Perimeter sealant that has split or peeled away
- Staining on stone next to old sealant
Hotel extensions and refits, at places such as Fifehead Manor Hotel, 1.2 miles north-west of Nether Wallop, usually run between busy periods, so the sealing is squeezed into short windows.
Questions to ask before you book
- Is the sealant right for the movement and the substrate?
- Their approach to joint depth and backing
- Whether primer will be used where the manufacturer specifies it
- How the existing material will be dealt with
Quoting for work in Nether Wallop
We price every job individually. The things that drive the figure:
- Travel to remote or island sites
- The total length or number of joints
- Specialist products, such as fire-rated or hygienic sealants
- Whether old sealant has to be cut out first
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.

For an accurate fixed quote, we need a clear picture of the site. Send us:

When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Cracked or spalling substrates that need repair before sealing
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Providing access systems for the work
