How we handle mastic sealing in Alresford

Across Alresford and the rest of Essex, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote, and site visits can be arranged. We work on shopfronts below residential blocks, balcony and threshold joints and communal entrances and stairwells, and the usual reasons a site gets in touch are repeated reactive repairs to the same buildings and damp patches beside frames. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Alresford, preparation and product choice get the time they need.

Owners with buildings around smaller places like Alresford often group mastic work so one visit covers several properties. One quote can cover a whole list of addresses.

Our workmanship is guaranteed for 12 months, in Alresford as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Questions we’re asked in Alresford

Will you work in a care home in Alresford without moving residents out?

Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

Our building in Alresford is near the coast: does that change the sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.

What paperwork can you provide?

We are CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

How do we ask for a quote?

You can use the quote form on this site; alternatively, ring 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How soon can the area be used again?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

What if the old mastic contains asbestos?

We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.

Mastic sealing around Alresford: points for this area

With the shore within about 2 miles, Alresford counts as a coastal location. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first; plan inspections around that. Central London is about 53 miles from Alresford. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide.

Buildings close to stations like Alresford station (under half a mile south-west of Alresford) are often flats over shops, with frame mastic to keep sound. If you own or manage units on a site such as Wivenhoe Business Centre, 1.6 miles west of Alresford, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. If your remit includes a building such as Alresford Primary School, frame and door mastic can be programmed for the holidays.

Diagnose, treat, sign off

We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a site in Alresford, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. A building-by-building inspection lists the failed joints.
  2. You get a fixed quote, per block or for the whole programme.
  3. We agree the programme and dates with you.
  4. Failed sealant is removed and the faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. We check the finished work and confirm the guarantee.

Different surfaces, different methods

Estate-wide resealing programmes

Consistent products and colours across an estate make future maintenance simpler and easier to manage.

Communal areas

Communal areas stay in use while we work. We work in sections so access is never blocked.

What sets the cost

To price the job, we consider:

  • Whether the work must be split into stages
  • Any access equipment needed
  • The size and state of each joint
  • Induction, permit and paperwork requirements

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

Before you send an enquiry

Good information means a firmer quote. Helpful details to send:

  • The site address and postcode
  • Your programme or deadline
  • Specification clauses that apply
  • Whether an asbestos survey exists

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Check sealant joints during planned building inspections
  • Group repairs into a planned programme
  • Protect low-level joints in entrances
  • Mention RAMS, insurance or CSCS requirements up front

Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges, and note the building and elevation.

The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing.

Leave it or put it right?

Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What you get with us

  • Over 20 years of commercial sealing
  • Health and safety: CHAS accredited
  • Specification-led, product-correct work
  • RAL and finish matching where the product range allows
