Replace Front door and frame, replace threshold, repair drip rail by main door, the front door frame and threshold has rotted and needs replacing, I have a new Pre-hung door from B&Q along with two hardwood thresholds, sills for this repair, one to replace existing threshold and one to be used for repairing a drip bar along the porch.
Nathan, Did an excellent job replacing my front door and frame and repairing damaged side drip sill, he cleaned up and removed all waste including the door. I would highly recommend Nathan.
