Flush Threshold Bifold Doors Liverpool
Achieve a continuous, step-free level transition from your kitchen tiles to your outdoor patio decking or paving.
Step-Free Accessibility & Seamless Design
A flush floor threshold sinks the bottom track flush into the finished floor height. This eliminates tripping hazards for young children and elderly family members while creating a striking, unbroken aesthetic between inside and outside.
Our technical surveyors assess your patio drainage options during your free site survey, recommending integrated ACO channel drains or rebated weather lip tracks for exposed coastal locations.
Fitted with heavy-duty stainless steel bottom rollers to ensure quiet, effortless sliding season after season.

Aco Channel Drainage Systems
To ensure complete weather resistance without high threshold steps, we install continuous stainless steel or black ACO slot drainage channels directly in front of the sunken track to channel rainwater away from internal flooring.
Low Rebate Weather Gaskets
Our rebated low thresholds incorporate dual EPDM weather seals that compress firmly against door sashes when closed, providing water tight wind resistance (up to Class 9A) while maintaining a minimal floor step under 14mm.
Wheelchair & Pushchair Accessibility
Compliant with Building Regulations Part M for accessible dwellings, flush sunken thresholds create barrier-free access for wheelchair users, pushchairs, and family members of all mobility levels.
Surveying Flush Thresholds in Liverpool Homes
Achieving a seamless zero-step finish requires careful planning before internal screed and external patio paving are completed. During our technical survey, our laser technicians measure finished floor levels (FFL) both inside and outside to ensure the sub-base is excavated to the exact millimetre required for flush track alignment.
Flush Threshold FAQs
Is a flush threshold completely watertight in heavy Liverpool rain storms?
When combined with an external ACO channel drain and dual-stage EPDM weather gaskets, rebated low thresholds provide superb weather resistance against driving rain and surface runoff.
Can flush thresholds be installed on existing timber joist floors?
Yes, our surveyors specify structural timber trimmer framing and tanking damp proof membranes to recessed tracks safely on suspended wooden floor constructions.
Does a flush threshold satisfy Building Regulations Part M?
Yes, low rebated thresholds under 14mm step height are fully compliant with Approved Document M for step-free disabled and wheelchair access into residential properties.
