Knock-throughs & new openings in Ashton-under-Lyne & Tameside

Planning a knock-through in Ashton-under-Lyne & Tameside? We open up kitchens, dining rooms and through-lounges — engineered, signed off and left ready for plaster.

Tameside's Victorian terraces and stone cottages in Ashton, Stalybridge, Mossley and Hyde, and the 1930s semis in Denton and Audenshaw, all bring knock-throughs and chimney-breast removals, with stone walls on the Pennine edge that are thicker than they look.

A knock-through joins two rooms into one — most often the kitchen and dining room, or the front and back rooms of a terrace or semi. We also form new doorways and widen existing openings, including large openings in rear walls for bifold or sliding doors.

Knock-throughs & new openings in Ashton-under-Lyne & Tameside: your questions answered

Do you cover Ashton-under-Lyne & Tameside?

Yes — Ashton-under-Lyne & Tameside and the surrounding area are part of our regular patch. Ashton-under-Lyne and the rest of Tameside fall under Tameside Council building control, or a registered building control approver.

Do I need planning permission for a knock-through?

Usually not for internal walls in a house. You do need Building Regulations approval if the wall is load-bearing, and listed building consent if the property is listed.

Can you form an opening for bifold doors?

Yes. We install the steel lintel or goalpost frame the engineer specifies and leave the structural opening sized to your door supplier's dimensions.

Will a knock-through make a lot of dust?

Cutting masonry is dusty, so the work area is sheeted off, dust extraction is used on cutting tools and the site is cleaned at the end of each day.
