Commercial sealant contractors for Crookham sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

For managing agents and facilities managers

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Crookham can form part of a wider programme across West Berkshire.

Commercial sealant contractors for commercial buildings in Crookham

Mastic Doctor has been sealing joints for businesses and contractors since 2005: we are CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. Let us know which site documents you need and they’ll be confirmed with the quote. We work on external facade joints, washrooms and tea points and kitchen worktops and splashbacks, and what we are called in for most is greasy, split joints in a kitchen or tea point and damp patches where an external joint has failed. Whoever orders the work in Crookham, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

The most common commercial job in Crookham is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

Work in smaller places such as Crookham tends to come one building at a time: a pub kitchen, a hall, a small office. We’ll want a full list and photos first, so the right products come on the day and nothing waits for a second trip.

A 12-month guarantee applies to all our work in West Berkshire. If an installation problem shows up, phone 01277 525 020 or email us and we’ll arrange a return visit.

What we can’t put right

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Water from a services leak rather than a joint
  • Old mastic that tests positive for asbestos
  • Misted, cracked or failed glazing units (a glazier’s job)

If in doubt, phone 01277 525 020 or email the details over and we’ll say what we think before you book.

What we seal

  • Floor and threshold joints
  • Window and door perimeters
  • Washrooms and tea points
  • Movement joints in walls and floors
  • Kitchen worktops and splashbacks
  • External facade joints

Shops, offices and hotels in and around Crookham

Rainfall across the South East, Crookham included, is lower than in many parts of the UK. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it. Less than 3 miles from Crookham there are at least three named estates and business parks. Each new occupier on a park like these tends to refit, from reception to staff kitchen.

Premises within reach of Thatcham station, 1.6 miles to the north-west of Crookham, often have busy frontages where joints are seen by everyone passing. If you run a unit on an estate such as Colthrop Industrial Estate, 1.4 miles to the north of Crookham, the trade counter, offices and staff facilities have joints to look after as well as the warehouse. A business with units at Colthrop Industrial Estate and Scion Business Park needn’t use two contractors for its sealant.

Crookham is about 3 miles south-east of Thatcham, in West Berkshire. Businesses, contractors and managing agents in Crookham can call on us for sealant joints, as part of our coverage of West Berkshire. We work across 140 places in West Berkshire, from busy centres to rural villages. Reading is covered too, some 12 miles away.

Anyone looking for commercial sealant contractors in RG7 and RG19 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

Nearby places we also cover include Hyde End (1 mile south-east), Goose Hill (1 mile south-west), Mill Green (1 mile south-west), Ashford Hill (2 miles south-east) and Plastow Green (2 miles south-west) for sealant joints.

Quoting for work in Crookham

The price varies from site to site. Expect it to depend on:

  • Access and working height
  • Working within restricted access windows
  • Location, for remote and island sites
  • The total length or number of joints

There’s no price list, since every building and every scope is different. Call for a quote.

Before you send an enquiry

A good diagnosis starts with the right details. Tell us:

  • When you need the work done
  • The postcode of the building
  • Whether the building will be occupied during the work
  • Specification clauses that apply

To get a fixed quote, ring 01277 525 020 or email a schedule or drawings with the site address and an outline of the work. Our quote form is another easy route.

On site: what to expect

Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. For a building around Crookham, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We begin with whatever information you have, whether that’s photos, a drawing or a list of locations, and a site visit is booked where it helps.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. We plan around your site hours and access windows, phasing the work where areas have to stay in use.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Preparing the site

  • Confirm the product named in the specification
  • Send your site hours and access windows
  • Tell staff and tenants when we will be in

Related advice

After the work

Regular inspection catches problems early. In particular:

  • Check the asbestos register before anyone disturbs old sealant in an older building
  • Keep a record of which joints were resealed and when
  • Keep washroom and kitchen extraction working
  • Add sealant to the planned maintenance inspection list

In washrooms and kitchens, extraction makes a real difference to sealant life. Fans that are broken or switched off leave joints damp for longer. It’s worth having fans checked while the sealant is fresh.

A failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Resealing early keeps the problem in the sealant and out of the building.

Leave it or put it right?

Fixing joints complaint by complaint is a costly way to manage sealant. Planning the work across a year or a portfolio means fewer separate visits and a predictable spend. We can help you prioritise, starting with the joints most likely to let water in. One visit to deal with every failing joint makes more sense than several trips to a place like Crookham. Photos of every joint help us quote for the whole job.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

What you get with us

  • Matching to RAL references, product permitting

Common questions from Crookham clients

Does your area include sites such as Colthrop Industrial Estate, near Crookham?

Yes, sites like Colthrop Industrial Estate are within our area, along with the rest of Crookham. Send details of the unit and the work through our quote form for a quick quote.

Is Crookham too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

How do you choose the sealant?

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.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Can areas stay open during the work?

Phased work can be planned so areas stay in use. Tell us your site hours and access windows and we’ll plan around them.

When can the area be used after sealing?

We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
