House Extensions / Renovations

Working with our architect we had plans drawn up and contacted the council to see if the extension needed planning permission. Planning permission was not required but building regs were required, so we liaised with the Wigan MBC planning office to ensure that building regs were complied with. Electrical certificates and a final sign off from the building inspector were also organised.

House Refurbishment & Extensions – Full Project Management by SJP Builders

One of the reasons SJP Builders is asked to do so many house extensions is that we offer the complete house extension package. This can include having your plans drawn up for you. Most customers already have plans drawn up but if you prefer we can discuss your requirements, suggest options to achieve what you are looking for, then have plans drawn up and submitted for you. Where appropriate we will involve a structural engineer and we also liaise with the planning officer on your behalf.

Following planning consent, we organise bricks, other materials, groundworks and drainage and arrange for the building inspector to visit at the relevant stages of the extension’s development.

We also take care of the certification of work required in the house extension. Certificates are required for gas, electrics, windows and doors.

House extension work can include:

Wall Tie Replacement

marsden-extension-052Over time, the wall ties in older properties will corrode. This often results in the outer wall bowing and eventually becoming unstable.

Horizontal cracking in brickwork, or render can be an indicator of wall tie failure. Ground movement or settlement can also cause cracking. A Structural Engineer would be the best authority to confirm the cause of this cracking.

If the cracks are considered to be due to wall tie failure, this can be investigated with a metal detector. Alternatively, we can sometimes view the ties from within the cavity, with the use of a torch and a mirror, viewing in the roof space at the top of the wall. Sometimes we can view the ties by removing an air brick. A further advantage of this process is that we can measure the width of the cavity which we will need to do to order replacement wall ties.

You may have either fishtail or twisted wire ties in your wall. Fishtail ties can expand enough to cause cracks and should be removed after the new ties have been fixed. Twisted wire ties will not rust enough to cause cracks, so they can be left in place.

Bricks potted with holes can be difficult to re-tie with a mechanical expanding type replacement and in these cases we may need to use resin fixing ties.

If you think that you may have a problem with corroded wall ties, call Simon on 01942 704662.
