    Hi folks,

    I had to move the the upvc door when levelling the floor.

    I took all the old trim off and now want to seal apply new upvc trim and seal the door edges.

    What is the best sealant to use? I remember about 5 years ago when the door was installed and the company had Dow 785 (I think)

    Please advise

    Dow make good sealants but then so do Soudal, they'll be twice or three times the price but it really is worth it, avoid no nonsense stuff from B&Q/screwfix, spec wise look for a Low Modulus Neutral Cure silicone sometimes referred to as Low Mod, avoid High Mod Acetoxy Cure - it just hasn't the flexibility and will pull away
