What affects the quote in York Town

The quote reflects the job in front of us. We look at:

  • The old material and how stubborn it is
  • The type of sealant required
  • The size of the job
  • Any working-time requirements on site

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

What to tell us for a quote

There’s no need for technical detail. It helps if you can tell us:

  • The rough size of the job
  • Where the property is
  • Access, such as stairs, a lift or height
  • Photos by email, if that is easy

Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we will come back to you with a quote.

Sand mastic for homes and businesses in York Town

Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. Typical jobs include mastic worn away on windows facing the weather and old sand mastic that has cracked, crumbled or fallen out, on brick reveals, period & listed homes and sash and case windows.

Around York Town, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows.

You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

When it is not the sealant

Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:

  • Putty and glazing repairs
  • Sashes that need overhauling
  • Decayed frames that need repair

If in doubt, call 0345 464 0079 or email us and we’ll say what we think.

What we seal

  • Period & listed homes
  • Brick reveals
  • Tenement windows
  • Sash and case windows
  • Stone surrounds
  • Timber door frames

Why it’s worth doing now in York Town

Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and blends with the stone or brick. Homes in smaller places like York Town can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

Why us?

  • A 12-month guarantee on all work
  • 4.9 on Google from 180+ five-star reviews
  • Anti-fungal sanitary silicone in wet areas
  • We never seal over old sealant

DIY sealant or a professional job?

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

A DIY attempt does not rule out a professional job. We cut it out and start again.

Looking after it afterwards

To keep the joints looking good and working properly:

  • Sort the mastic before the decorators arrive
  • Ask a joiner to look at soft timber first
  • Make sure water runs off the sill
  • Check the mastic when you check the paintwork

When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.

Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.

Do you need sand mastic in York Town?

Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows.

Signs it’s time to call us include:

  • Mastic that needs renewing before redecorating
  • Mastic worn away on windows facing the weather
  • Modern sealant on a period surround
  • Open joints round the window box

If you look after a building such as South Camberley Primary and Nursery School, larger buildings have plenty of frames, and the mastic around each one ages.

Before you book anyone

  • Whether they seal over old material or remove it
  • When the joint can take water or movement
  • How much experience the applicator has
  • What product goes in the joint

Do the sealants smell?

Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.

Do I need to be at home?

We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.

What do you put in the joint?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.

The process

The work is kept neat and contained to the area we’re working on. The job usually takes a few hours for a single window, longer for several. In a smaller place like York Town, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.

  1. First, we look at the surrounds with you and agree what needs doing.
  2. We rake out the old mastic and clean the joint.
  3. Deep voids are packed so the mastic is the right thickness.
  4. We mix the sand mastic and apply it by hand, shaping it to the joint.
  5. The finish is dressed so it sits neatly against the stone or brick.

How to prepare

  • For business premises, tell us about site rules or sign-in
  • Clear the area around the work
  • For indoor joints, keep the area dry beforehand if you can
