Mastic sealing across Ipsden

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How we handle mastic sealing in Ipsden

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. If you are dealing with no planned programme for sealant and draughts at frames across a block, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Ipsden from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Around smaller places like Ipsden, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Frames, entrances and external joints in Ipsden

Ipsden lies roughly 43 miles out from central London. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide. Ipsden is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.

If you’re responsible for a building such as Church of St Mary, frame and door mastic needs the same attention as any other property. If you own or manage units on a site such as Vanalloys Business Park, 2.9 miles to the east of Ipsden, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Ipsden is about 8 miles north-west of Caversham, in Oxfordshire. Our applicators travel to Ipsden for work on mastic joints. Ipsden is one of 423 places we cover in Oxfordshire. Sites around Reading have their own page, about 9 miles away.

Business premises anywhere in OX10 are within our area for mastic joints. For a building on The Street, Fir Close and Crabtree Corner or nearby, send details and we’ll quote for mastic joints. We also cover Heath End (2 miles east), Checkendon (2 miles south-east), Woodcote (2 miles south), Nuffield (2 miles north-east) and Stoke Row (3 miles east). A short drive away, we cover Oxford (14 miles north-west), Didcot (8 miles north-west), Abingdon-on-Thames (12 miles north-west), Thame (14 miles north), Wantage (15 miles west) and Henley-on-Thames (8 miles east).

Our process

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. Jobs in and around smaller places like Ipsden are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We check the asbestos register for older buildings and look at the joints.
  2. A fixed quote covers the joints, products and order of work.
  3. Failed mastic is removed completely.
  4. The joints are prepared and resealed with the right product.
  5. We finish each building before moving to the next.

What we need from you

  • Make sure the joints can be reached
  • Share your working hours and any access restrictions
  • Arrange parking or a loading space

Getting a fixed quote

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Advice

Why it’s worth doing now in Ipsden

Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. Halls, stores and units around places like Ipsden may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote when you’re ready.

Why us?

  • 12 months’ guarantee on every job
  • Products installed to the manufacturer’s instructions
  • Joints cleaned back to sound surfaces
  • Health and safety: CHAS accredited

Common questions from Ipsden clients

We manage a building near Cholsey station. Can you help?

Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.

Is Ipsden off your patch?

Not at all. Ipsden is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

What guarantee do you give on resealing?

A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.

Does the weather affect the work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Do you work with property factors and landlords?

We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.

How do you handle work on occupied blocks?

Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so it can be arranged.

Doing it in-house

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

What the job involves on each surface

Estate-wide resealing programmes

Housing associations and agents often manage many similar blocks. We quote building by building and work through them in turn.

Commercial and mixed-use buildings

Tenants in commercial buildings need to keep trading so the work is phased.

Honest limits

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Failed window or door frames, which need a window contractor
  • Water coming in from the roof or rainwater goods
  • Asbestos-containing sealant, which we don’t remove

Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we’ll tell you honestly.

Surfaces we seal

  • Window and door perimeters on blocks
  • Balcony and threshold joints
  • Communal kitchens and washrooms
  • External wall and movement joints
  • Communal entrances and stairwells
  • Shopfronts below residential blocks

Signs you need mastic sealing in Ipsden

Many failed joints were sealed without backing rod so the mastic is bonded on three sides. That three-sided adhesion stops it stretching and splits as the building moves.

If one of these sounds familiar, it’s time for a closer look:

  • Complaints coming in block by block
  • Water getting in round frames after rain
  • Patchy repairs in mismatched sealant
  • Communal area joints that look neglected

Historic properties like Basildon Park, 4.7 miles to the south of Ipsden, show the age of some local stock, where frame mastic must suit soft brick or stone.

What your quote should include

  • How joint depth will be controlled
  • Health and safety accreditation such as CHAS
  • How they’ll work around occupants
  • Whether primer will be used where the manufacturer specifies it
