How a job runs

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs in and around smaller places like Over Wallop are usually planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

How we handle facade sealing in Over Wallop

Facade sealants sit in the sun, rain and frost every day, and they wear out over time. Life depends on movement, weathering, product choice and the quality of the original work. When it fails, the whole bead is cut away and the joint rebuilt. If you’re dealing with weathered facade joints that have lost their grip and new sealant peeling off old mastic, we can put it right, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Over Wallop is the same: the right product in a properly prepared joint.

In the countryside around places like Over Wallop, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Quoting for work in Over Wallop

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Induction, permit and paperwork requirements
  • The product specified
  • Access and working height
  • Quantities, in metres or numbers

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What to include in your enquiry

To price the job accurately, we need to understand the site. Useful things to include:

  • Rough lengths or quantities, or drawings if you have them
  • Clear photographs of the problem areas
  • Where the site is, with the postcode
  • When you need the work done

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings you can plan around. For a chat about it beforehand, speak to us on 01277 525 020 or send photos by email.

What we can’t put right

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Providing access systems for the work
  • Replacing glass or failed glazing units
  • Cracked or spalling substrates that need repair before sealing

Not sure which it is? You can ring 01277 525 020 or use the quote form and we will tell you honestly before you book.

What we seal

  • Window and door perimeters
  • Stone and brick facade joints
  • Cladding panel joints
  • Perimeter joints where frames meet the structure
  • Coping and flashing joints
  • Shopfront frames

Common problems we fix in Over Wallop

Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead, and the patch soon lifts.

What tends to prompt an enquiry:

  • Old perimeter mastic that has dried out
  • Unsightly perimeter sealant on a visible elevation
  • Cold air coming in at window perimeters
  • Patch repairs that keep failing

Hotel extensions and refits, at places such as Fifehead Manor Hotel (0.5 miles south-east of Over Wallop), usually run between busy periods, so the sealing is squeezed into short windows.

Comparing quotes

  • Who will actually carry out the work
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Their plan for phasing and protecting the area
  • Their public liability cover

Questions to ask before you appoint anyone

Leave it or put it right?

The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. Halls, stores and units around places like Over Wallop may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Questions we are asked in Over Wallop

What documents will you need to give us for a job in Over Wallop?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.

Is Over Wallop too small for you to travel to?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Do you replace windows or glass?

No. That work needs a glazing specialist. What we seal are the joints around frames and panels on commercial buildings.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Should we check old sealant for asbestos?

It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register. Suspect material is left alone until it has been tested.

Do you have public liability insurance?

Yes. We are fully insured, including public liability cover.

Can the building stay open while you work?

Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.

Contractors’ notes for Over Wallop

Over Wallop is about 69 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme. Rainfall across the South East, Over Wallop included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.

When a school such as Wallop Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Precast concrete panels

Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod with primer where the product requires it.

Window and door perimeters

Frame materials vary, and so does the preparation. We clean and prime to the sealant maker’s guidance for each surface.
