Installing a Fence on a Sloped Site

Bob talks with Jay Triandafilou from Architectural Fence Plus about the fencing installed on the side and backyard of the home in Melrose. The fencing was built using white cedar, a strong and long-lasting wood. The fence posts were installed using a concrete mix, which can promote rot if done incorrectly. Triandafilou explains that the base of the posts were placed into a 36- inch hole. Six inches of dirt were put into the hole and concrete was then added. This method does not create a total seal and allows water to pass through the dirt, between the wood and the concrete. The concrete provides stiffness and stability for the fence posts. The post should not be totally encased in the concrete. The fence on the side of the home has three stalls, which will provide space for a shed, a planting area, and a place to keep trash. In the backyard, there was an existing chain-link fence that needed to be taken down. The land was rocky, which made digging the 36-inch holes for the fence posts difficult. When placing fence posts, a good rule is one third of the post should be placed below ground and two thirds above. Triandafilou explainsthat the area where the fence was installed is a sloped site, which posed some challenges. Triandafilou and his team made the fence sections off site, but in some cases the board sections were created on site to accomodate the slope. A finished cap was added to the top of the fence to keep out rain. The top of the fence was cut to allow this cap to be installed. Triandafilou explains the "clean side" of the fence (the face without the horizontal rails ) was put in place facing the neighbors. In the back of the house, the clean side was installed facing the home.

" All right the major landscape improvement that we're doing to the side in the back of the house involves fencing and Bob this all white cedar the is right yes sir so what do. Why is that the best choice for this kind of fencing. It's. Would dense enough not -- species it's local it is. Impervious to rot its long lasting long lasting yeah now one thing that I want to ask is I've always thought that mixing concrete. In. In a hole and putting in an a hole surrounding a wood post of any sort is a bad idea doesn't it promote rot."

" It does if it's done improperly. There is a correct way of doing -- what we do is we set a post to approximately 36 inch depth. -- we'll throw all part 36 inches of material dirt back in the hall of dirt and then we'll add the concrete that way doesn't create a total seal. It allows a lot to pass through the wood between the wood and carved from the concrete is there for stiffness stiffness stability and it's remains the elevation."

" Also they don't heat is not to totally in case. That post in concrete current -- you did that you would be trapping moisture in the wood yes and that's accelerates the writing process. I gotcha all right well what what are we creating right here this almost looks like shower stalls at the beach club here."

" Yeah it is in the sense. Basically Sarah came to us and our homeowner your homeowner she said that very tight site and she would have wished she could have a shed planting area and a trashed them. Sources are we can give that -- we have that's spot on the side and this is basically what this."

" Create so essentially got the fence going along the property -- putting up these little wing walls are we going balances on and and we'll have an enclosure for trash let's talk about what you've already done though because when you got here you had to deal with. Federal rough site was the first thing had to go to work on what we came here first Bob we had. There was an existing chain link fence that was up in the back line. With. Some heavy growth so we had come in and cut the growth and also remove the -- fast. What about the digging on the site is a very rocky isn't there some ledge around here there's quite a bit rock here and -- fact were struck. Part of Iraq in the holes as we're digging -- loose material and also some solid material. Of these posts have to be dug to a 36 inch depth. So we find it quite frequently that is why the cement also helps is the depth because of the the frost heaves that we encounter in -- requirements it's for the frost as well as stability of the fence six foot high fence. Needs a certain amount in the ground -- two thirds of the height must be set in in the ground. Two thirds two thirds above and 13 below current -- OK and what about the actual panels these are made back in your shop and then you install them on site that's. You've got a sloped site how do you deal with that well that's -- that's an interesting. Question we have to do with the call racking the sections. Which basically takes a section that's built square -- and actually slopes the boards. To make up for the difference in the elevation in the height of the ground OK. And you can do that even though you got double nailing on all these boards at that point they go."

" To a certain extent sometimes they've -- reach a point where they won't rack any further in in that case we have to build the panels on site. Okay what you -- here what about the caps. The caps the fence cap on the top of the fence. Is it is a finish piece as Rollins and it helps with the rain. Basically we have to sometimes. You get into position whereas the boards. On. Extremely racked situation. You -- stagger yeah so are you have to cut. The top of the boards and -- for the -- it over because there's only about a half inch. -- that itself."

" This as a soffit yeah now putting up fencing on a sloped site has got to be the hardest job now it's not -- All right so most fencing has. Well they're both nice size -- one side is. Clear like this and the other side has the rails exposed. For a and so would how do you choose which side faces in what direction."

" That's up to the homeowner -- is really in -- system this town ordinances that specify which you can who gets which side. Basically this is what we call the good side of the beauties I've -- due to side in in the backside. Of course has a three cause off the rails and -- done here well we've we've done it both ways here Bob as a matter of fact the rear fence actually we turned the good side into the homeowner OK and then a sidelined we turned the rails inside the home so we didn't the beauty side to the neighbor correct and the neighbor's very close to the fence well it's a beautiful fence things."

Removable Swimming Pool Safety Fencing
Removable Swimming Pool Safety Fencing

Bill Jasper from the Baby Barrier Pool Fence Company joins Bob for the installation of the removable Baby Barrier that will add a layer of protection for young children around the pool. Vertical aluminum poles with steel inserts for strengthening are set in the pool deck to receive the barrier panels. Jasper explains how the construction exceeds code requirements that state the fence be able to withstand more than 53 pounds of pressure. This fencing can withstand up to 80 pounds of direct pressure and has a latching gate that is child-proof by design. The panels themselves are PVC-coated wire mesh. The cost for the full installation with a ten-year warranty is between $1,500 and $2,000.

Dog Fence Options
Dog Fence Options

Here s another great tip from BobVila.com. While we all know they don t like to be fenced in, after thousands of years of domestication, dogs need boundaries to be safe. Fortunately, dog owners have lots of options to choose from when it comes to fences. If your yard isn t fenced or you d simply like to keep Rover out of the lily bed, you can build him a dog run with 4- to 7-foot wire or polyethylene rolled fencing. Staked into the ground without the use of heavy equipment, this dark mesh fencing is designed to be easily movable, strong and unobtrusive. You can also find chain link or powder-coated metal kennel kits to keep your dog safe outside and limit his range. Look for fencing that s 12-gauge or heavier and doesn t include aluminum fittings, which can weaken over time outside. If a kennel or dog run isn t something you want in your yard, an underground electronic fence may be the answer. Some brands are even wireless now so no ditch digging is necessary. As the dog approaches the fence boundary, his collar emits first a warning sound and then an electronic stimulus, or correction, to keep him away. To avoid confusing your dog, training has to accompany this system. Electronic fences are available with incremental strength levels for training and for different sized dog breeds. You don t want your dog escaping and getting injured because of a dead transmitter battery so look for a system with the longest battery life possible. And remember to check the battery regularly.

Installing a Maintenance Free Vinyl Picket Fence
Installing a Maintenance Free Vinyl Picket Fence

Bob meets Todd Skulksy of Perfection Fence as he installs the classic New England-style vinyl picket fence. This product has a wood look and is made of mono-extruded vinyl so that it has only one layer and will not show nicks or discolorations over time. The fence is installed without mechanical fasteners and has been engineered with the crimps molded into the rails. The rail locks into the post piece and the crimp holds it in place. Perfection Fence vinyl fences come in different styles, this one with traditional New England features like the Colonial cap and ball finial for the top. Skulsky explains that these fences are moderately priced and cost less than finished wood fencing, but more than an unfinished wood fence. They are maintenance free, however, which will save money over time.
