Bifold Door Overhaul & Seal Replacement in Thame

A homeowner in Thame, Oxfordshire, reached out to Doorveloper after noticing their Origin three-panel bifold doors had dropped, making them difficult to operate and reducing their weatherproofing. Our team attended to carry out a full overhaul and service, ensuring the doors were restored to smooth and reliable operation.

What Does a Full Bifold Door Overhaul Include?

At Doorveloper, our full overhaul process is designed to bring your bifold doors back to near-new condition. This includes:

• Removing all glass panels – Taking the doors back to square one allows us to fully reset and adjust them.
• Thorough inspection & adjustments – We check all hinges, rollers, and alignment points, making any necessary repairs or adjustments along the way.
• Reinstalling the glass correctly – One of the most common causes of bifold door issues is incorrect glass alignment. We ensure everything is precisely set to manufacturer standards.
• Final testing & quality check – The doors are checked for smooth operation, proper sealing, and effortless movement.

As part of this job, we also replaced the Large Qlon Seals on both the top and bottom sashes, which play a vital role in insulation and weatherproofing. Over time, these seals can wear out, leading to draughts and reduced efficiency. By sourcing and installing high-quality replacements, we ensured the doors were properly sealed and performing at their best.

With the overhaul complete, the doors were fully restored to smooth operation, improved weatherproofing, and effortless use. We’re so confident in our process that every bifold door overhaul comes with a 12-month guarantee for peace of mind.
