The hardwood sill of this set of French doors was severely rotten to the point where the central section could be pulled out by hand. A combination of the outside ground level and a poorly fitting weather bar meant that it didn’t ever get an opportunity to dry out.

After removing the old sill, we set about making a new one on-site using Accoya, which will perform much better than the hardwood original in wet conditions. We also did away with the weather bar design, instead using a more robust rebate to seal the doors.

With the new acetylated pine cill bedded and jointed, we were left with a more weatherproof and resilient set of doors at a fraction of the cost of replacement.
