That is Oriented Strand Board (OSB), typically used for sheathing.  Looks like it has been used exposed to weather, which is not its intended use.  There is no reasonable repair for that, other than replacement... with materials suitable for whatever the application might be.  Call a professional contractor.

I agree with what Yuri said and would like to add that it is imporatant to have it removed properly so as not to cross contaminate. Mold spores are microscopic in size and easily dispersed if not handled correctly.

The leak and mold are time sensitive. Mold can be hazardous to your health. Dealing with mold properly means removing the sheetock and insulation once the leak is fixed. Don't let anyone tell you they can seal it in place and paint ove it. It must be removed. The foundation work can get vey expensive if you wait too long so don't put that off too long.

Hope this helps.

Bulb info should be on base of bulb. Many internet sources for older and unique bulbs. May want to use multimeter to check contacts of socket to be certian power is reaching an inserted bulb.

It can definitely be repaired, it would need extensive spackling, most likely with 2 part Bondo, then sended primed and painted.

this is something that should not take more than 6-8 hours in total, obviously it does require some skill.

The picture shows the door is stained wood.  The wood is repairable but the door will have to be painted or the repairs will be visible.

Do you know if the estimate from Home Depot was to replace the entire door assembly or just the (door(s)?).   If they estimated the cost including removal and replacement of door jambs, threshold, and door trim, then an alternative that could cost less would be to replace the door slabs only and keep the existing jambs and trim.

Cut the screw if the other methods fail.

Its painted; go to hardware store.  Buy spackle and sand paper.  Sand it down, spacke the scrapes.  Sand the spackle.  Repeat again, though after this spackle prime the door.  Then spackle and prime and paint.  You are looking at spackle 3 or more times, priming it more than once and then paitning two coats.  Alot of work.  But less expensive than a new door.  

Try securing the anchors with ViseGrip pliers, but be sure to only secure the anchor, not touch the screw.

Good afternoon,

The picture of the door looks to have polyurethane applied. If this is the case, that’s most likely an oil based finish. If you are trying to apply a latex base interior paint it will not work unless the finish is completely stripped off.

With out physically seeing this myself I can only speculate this to be the issue. The proper tradesmen to contact would be a Painter.

Thank you for inquiring with Ferris Home Improvements but unfortunatley this is not in our scope of work. Feel free to contact us with any questions or future projects. Have a great afternoon

If you do not know what you are doing, hire someone who does!  

I'm actually not seeing a wire sticking out of the wall to connect to (in either picture).  There should be a wire sticking out somewhere, unless they also clipped that off, or stuffed it behind the window.  Also, did they leave behind the other half of the sensor?  As others said, wireless may be an option if all else fails in your scenario. 

As with the previous comments, you can use sandpaper to smooth out some of the damage, but be sure to rub the scratches along the grain of the wood. Next, apply mineral spirits (these are solvents made from paint thinner and petroleum) over the sanded area. Spread on wood filler with a Spackle knife to the damaged parts and allow it to dry as per the filler’s directions. After the wood filler has dried, lightly sand the area once again and brush away any dust before priming and painting your door.

While the image shows damage to the inside of your door, your pet may try scratching on the outside of door and its weather stripping in an attempt to be let inside. In order to prevent future damage to that part of your door, you can add a piece of vinyl lattice that matches the color of your doorframe. Cut the lattice to the length of the doorjamb. Place it over your foam weather stripping. Check to see that your door continues to close properly. Use finishing nails every foot to tack the vinyl lattice securely in place. A small amount of spackling will cover up the nail heads. Now the lattice will protect your weather stripping from further damage.

The right type of door for your home can make a huge difference. We install ProVia doors and they offer DuraGuard Series Storm Doors, which are ideal for keeping pets safely inside with their non-removable stainless steel screening.  

Best of luck with your dog and your door repair!
