What Rot

Before I actually started cutting away the rotted sill, I wanted to shore up some of the nearby framing.  The ancient hot water heater I've mentioned in previous postings (Hot Water Detour and Revisit to Hot Water) was installed a lifetime ago and in such a way that has a bearing on the sill work I'm involved in now.

In order to get the big stone lined tank into the basement, the installers cut a hole in the floor right inside the front door.  They also cut right through a 7" diameter log that served as a floor joist.  They patched up the hole with some new flooring and tacked a couple of scraps to the freshly cut ends of the log to serve as headers for the severed joist.

The tolerance of wood frame construction for this kind of butchery is pretty amazing.  It really looks like the floor should have collapsed a long time ago, but I suppose between the old plank flooring that's an inch thick, the hardwood flooring above that, and the scrap pieces nailed in as headers, the load that the old floor joist was meant to carry is spread out.

Newjoist3smNow I was about to cut into one of the framing members that was probably carrying some of that extra load.  Before I started, I thought it best to replace the severed joist.

The challenge was the space I had to work in.  A mix of plumbing, heating ducts, and electrical wires converge on that spot.  Getting a new joist in there meant removing staples on the electrical wires so they could be moved aside and then threading a couple of 12 foot 2x6 boards through the ducts and plumbing so they could be sandwiched together and mounted. I also needed to jack up the new joist a bit before mounting it in its joist hanger.  It seem the floor had sagged a bit over the years.

Cuttingaway_2 With the new joist in, I was ready to start cutting away at the rotted sill.  There's still the issue of the wall studs that are supported by the sill, and how much sill I can cut out without providing support for those. There are 4 in question. The two on either side of the front door weren't getting any real support from the sill because of the rot, so I'm not worried about those.  The two studs on either side of those, however, may be carrying some load.  I'm relatively confident that I'll be alright taking the sill out from under those if I have to.  Again, the wood frame has the ability to transfer its load through the sheathing and across the top plate. It's not like removing one leg of a three-legged stool. It's more like taking 4 legs from a 60 legged stool.  Still, I'll be removing pieces of the rotted beam carefully, and plan on providing temporary support where I can.

Sill Exposed

Thresholdrot0001 With the days of summer waning I figured I better get started on at least one of the exterior projects I planned for this year.  The sill under the front door threshold is severely rotted and needs to be replaced.

I've been pretty confident all along that the awful looking rot was limited to that one area but I really couldn't be sure until I removed some siding to have a look.  The siding on Chez Melendy is cement asbestos shingles.  These shingles were probably added to the house sometime in the 50s when asbestos was all the rage and before it was deemed a hazard.  The shingles are fireproof and are a good protective siding with decent insulating qualities.  They don't pose the same hazard as other forms of asbestos because the asbestos is trapped in cement.  Unless the shingles are pulverized in some way, the asbestos remains encapsulated.

Sidinglayers Knowing the lack of danger posed by the shingles didn't keep me from being cautious, however, so I donned my fine-particulate respirator and got to work removing the first two courses of siding.  The shingles are strong when mounted flush to the house but are brittle when removed.  I couldn't help but break some as they came off, and it was for this reason that I wore the respirator.

Note: Asbestos particles are microscopic and can pass easily through your basic 2 dollar dust mask. An OSHA approved fine-particulate respirator is the only way to go.

Once the asbestos shingles were removed, I was ready to remove some of the original siding that was underneath.  I was happy to see that the original siding is in pretty good shape.  At some point in the future I'd like to remove all the asbestos shingles and go back to the original clapboards to bring out the original charm of this old cape cod style cottage.

Sillexposed0001 With all the siding removed from the lower 12" of the house, I could see the condition of the sill beam all along the front. Happily, it's not in real bad shape after a hundred and fifty years of existence.

The real work is ahead of me though as I need to chisel away the rotted section and then use pressure treated lumber to replace what's been removed.  I'll be looking for advice from some local builders as I start to put it all back together.  This section of the house is critical in that it's susceptible to moisture and, if not insulated properly, can provide a place for cold air infiltration.  I want to get this job right the first time, and completed before the snow flies.

Movin' On Up

Movinup There is still plenty of work to do on the upstairs, but enough has been done to allow us to start using the space.  I would've liked to strip and urethane the hallway, trim out the windows, paint hallway, etc. etc. but good enough will have to be good enough for now.  The non-essentials will have to wait until after I get the upstairs bathroom tiled and the tub, toilet, and sink installed.

The move itself was not without some pain.  After cleaning up from my last task of putting another coat of urethane on the baseboards, we tried to move the queen size mattress up the stairway.  No go.  The stairway is steep and narrow and is accessed through a doorway entrance from the side.  It's one of the old-house charms that grabbed me the first time I saw it, but now it was getting in the way of progress.Tightstairs

For the past year I've struggled to get building materials and large power tools around the corner and up the stairs.  All the while, I've stayed in denial about how we were going to move our bed and other furniture upstairs.  Well now the dilemma faced us head on.

The only way we were going to get the queen-sized mattress upstairs was by busting through the wall at the base of the stairs.  I was half-prepared for this.  When framing the downstairs, I deliberately left that wall in place with its old hand-split lathing exposed hoping we could keep it.  It was one of the few remaining vestiges of the original house.  In the back of my mind, however, I knew that it might need to come down to move up.

Sadly, I took the hammer and pry bar to the old lathing and opened up a space for us to get the job of moving done.  The new opening gave us just enough space to get our bed and dressers upstairs.

So tonight, after two years of living in the house, we'll spend our first night in the Master Bedroom.  Happy birthday to me.Movedup

Demolition

Lrdemo The first project I got into with Chez Melendy was the complete demolition of the interior walls.  This was a pretty drastic measure considering it meant I was going to throw away a good part of the house that I just spent a quarter of a million dollars on, but there were several reasons I felt it best.

The house had never been renovated since its construction, aside from modernizing improvements such as indoor plumbing and electrical service.  It was good that nobody had gone in and destroyed original details that might be worth saving but it was bad that there was no insulation; the electrical was a patched together system that included remnants of every kind service since its invention (knob and tube, cloth insulated 2-conductor, metal conduit, and romex); and there were a variety of toxic materials covering the walls and floor such as lead paint and asbestos.  It was also bad that the couple who lived there prior were heavy smokers.  The plaster walls were virtually imbedded with stale tobacco smoke. Why did I buy this house you ask?

Kitchendemo I imagine that few people embark on a gut renovation project with any real knowledge of what they're getting into.  On paper it makes perfect sense, get rid of everything you don't want then rebuild and restore the house to your liking.  Demolition can be fun, right?  Get out your frustrations on tearing apart some walls, and all that.  Strap on a dust mask grab a crow bar, and go to it.  Unfortunately the fun of destroying walls fades pretty fast, and the work of gutting a small house takes an enormous amount of physical energy and much longer than you might expect, not to mention the bleak task of dismantling something that someone else put together through hard work and sweat 100 years prior.

The first thing to consider in any demolition project is disposing the waste.  Getting rid of construction and demolition debris (C & D as it's know in the waste disposal business) is not cheap.  The best option is to rent a Dumpster.  Disposal and recycling companies provide Dumpsters in sizes from 1.5 cubic yards to 40 cubic yards on up, and charge handsomely using a variety of fee schedules.  If you've got a big project, try to find a company that doesn't charge a time-based rental fee.  Despite your best hopes of completing demolition in a given amount of time, like every aspect of a renovation project, it's going to take longer.

Debripiles Because my town has a transfer station that provides a C & D Dumpster, I opted to haul the debris myself.  It was a substantial savings but meant handling what turned out to be tons of material a few more times than if I was throwing it into a Dumpster parked in the driveway.  Looking back, it's difficult to say whether this was right way to go.  I could have saved myself a lot of heavy lifting by spending more on a disposal service, but it's also true that the money I saved meant more available for making improvements to the house down the road.

The tools of destruction are basic.  A flat pry bar was the handiest of all.  It worked great for pulling old plaster away from its wooden lathing, poked holes in wallboard with one swing, and yanked nails will little effort.  I also wielded a small sledge hammer for loosening up the more stubborn plaster and boards, used a shovel to clear the floors, and carried it all away in contractor bags

A reciprocating saw was indispensable and has remained so throughout every stage of my renovation project.  Don't skimp on selecting one of these.  There seems to be no end to uses for this fine invention.  Get a good one and it'll serve you well for years.  A word of caution though when wielding a sawzall: be sure of what lurks behind the wall.  It's easy to overlook the possibility of electrical service or plumbing runs when you're hell-bent on destruction, and the ease and speed at which these saws work can get you into trouble quickly.  Another word of caution is: be aware of what kind of wall you're destroying.  Is it simply a partition, or is it providing structure to the floor above?

Wallflower But even before picking up the tools of destruction, you'll need to dawn the equipment of health and safety.  Don't get started on demolishing an old house wearing a bandana wrapped over your mouth and nose.  And don't think a dust mask held in place with a rubber band is going to offer you sufficient protection.  Old houses contain all kinds of materials that can become serious health hazards when released into the air as particulate.  The microscopic size of many of these particles pass easily through your 10 cent dust mask. 

Invest in a professional respirator that provides HEPA certified protection from fine particulate, and read the instructions closely.  An improperly worn respirator is as good as wearing none at all.  Wearing a respirator takes a little getting used to but consider it as another tool of the trade, complete with a learning curve.  Your lungs will thank you.

I donned a Tyvek suit for all the demo work as well.  It made it easy to leave the dust at the worksite and not bring it home in my hair and work clothes.  I also left my shoes at work.  Anything that might carry harmful particles home to where the family might inhale them I did my best to leave amongst the debris.

Treasure2_1 After all this you might wonder why not pay some unskilled labor to gut your old house project. There's certainly an argument for that.  But there were also many decisions I made while busting things apart, especially what NOT to destroy.  The charm of an old house is the sum of many little things that can easily get swept away in a demolition.  A piece of old door hardware, a fragment of wallpaper, an odd-shaped lintel.  These things may seem like junk to some, but to the old house restorer, they can be irreplaceable. And you also never know what treasures you might find hidden in the walls....
